DNS Records
In order to find resources on the network, computers need a system to look up the location of resources. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. This video looks at the DNS records that contain information about resources and services on the network. The client can request these records from a DNS server in order to locate resources like web sites, Active Directory Domains and Mail Servers just to name a few. http://ITFreeTraining.com/handouts/dn... In this video This video will look at the following DNS records: Host (A and AAAA): Contains IP Addresses for IPv4 and IPv6 hosts Alias (CNAME): Works just like a shortcut for files except for DNS records. Mail Exchange (MX): Holds the address of mail servers for that domain. Service Record (SRV): Holds the address of services on the network. E.g. Active Directory DC's. Start of Authority (SOA): Contains information and configuration for a zone file. Name Server (NS): Contain the address of other DNS servers for that zone. Pointer (PTR): Reverse look up record allowing a hostname for an IP Address to be look up. Host (A and AAAA) The host record is used to store the address of a hostname. "A" is used for IPv4 and AAAA (Quad A) for IPv6. These can be created manually in DNS or if dynamic DNS is enabled and the client can register its hostname and thus its IP Address with the DNS server. Alias (CName) A canonical name or CName record provides an alias service in DNS. A CName effectively points to another A or Quad A record. When the client requests the hostname that is contained in the CName, they are given the IP Address that is contained in the A record or Quad A record. The advantage of a CName is that it can provide a simple name to the user rather than a more complex server name. For example, instead of having to remember FS27 for the local file server, a CName of FS could be used to point towards the server FS27. CName's can also be used to transparently redirect network traffic. For example, if you changed you mind and wanted to redirect the user to FS28 you would only need to change the CName record to point to FS28 rather than FS27. It should be remembered that the old record may exist in the client cache and may take some time to expire. Mail Exchange (MX) The mail exchange record contains a mail server that is able to process mail for that domain name. When a mail server wants to deliver mail, it will perform a DNS lookup asking the DNS server for an MX record for that DNS Domain name. The mail server will then attempt to deliver mail to that server. The mail server does not need to have the same DNS name as the mail that is being delivered, it simply needs to understand how to process mail for that DNS domain name. The MX record also has priority value that can be configured. If two or more MX Exchange records exist for the same DNS Doman name, the MX record with the lowest priority will be tried first. If this fails, the MX record with the next lowest value will be tried until the mail is delivered. Often large companies will have multiple mail severs for incoming mail. In some cases, these additional mail servers may be located on different sides of the globe in case there is a long network outage. Service Record (SRV) Service records allow clients on the network to find resources on the network. Active Directory creates a number of service records in DNS to allow clients to find resources like Domain Controllers. This is why Active Directory cannot operate without DNS. A single service record has a number of data fields associated with it. These include, service, target, port and priority. Service records are normally created automatically by applications assuming that your DNS server allows dynamic updates. Start of Authority (SOA) There is one start of authority record (SOA) for each zone. Even though the SOA is technically a DNS record, essentially modification of the SOA record is performed through the properties of the DNS zone. Looking at the data in the SOA record, you can configure options for the zone like the primary name server for that zone (DNS servers that hold the master records for the zone), the e-mail address of an administrator, serial number (Incremented each time a change is made in the DNS zone) and the refresh time for the zone (How often a secondary zone should query a master for changes).

Creating DNS Records using Microsoft DNS
This video will look at how to create some of the more common DNS records on Windows Server using Remote Administration Tools for Windows 8. Download the PDF handout http://itfreetraining.com/handouts/dns/records-demo.pdf Demonstration The Windows 8 computer has Remote Server Administration Tools installed which means it can be used to administer Microsoft DNS Server running on another computer. 1) To open DNS Manager, open charms by moving the mouse pointer to the top right of the screen and then selecting the icon Administrative Tools. Inside Administrative tools is the shortcut DNS to run DNS manager. 2) When you first run DNS manager it will ask which computer you want to perform administration on. You should enter in the name of the server that you are running Microsoft DNS server on. 3) In DNS Manager, DNS records are organized into containers. Most of the general DNS records that you will create are located under Forward Lookup Zones. 4) Under Forward Look Up zones is a container for each Forward Lookup Zone. In this container are the DNS records that have been created for that forward lookup zone, however some of the DNS records do not appear in the container. If you right click the zone file and select properties and then select the Start of Authority tab, this shows all the data that is contained in the SOA record. Every zone has an SOA record. Since there is only one SOA record, and there has to be one, Microsoft decided to make it so the SOA record could only be modified by changing the properties of the zone. Start of Authority (SOA) Primary server: Is a server that holds the primary zone for that zone. The primary zone is a server that contains a writable copy of the DNS data. Responsible Person: This is the e-mail address of a person who is responsible for looking after that zone. The value is only valid if the @ sign is changed to a period. Name Server (NS) This data is accessed via the properties of the zone and selecting the tab Name Servers. Servers that appear in the name servers tab are considered to be DNS servers that hold the best source of information for that zone. They do not have to have a writeable copy of the zone file, it is just that they need DNS servers that contain an up-to-date copy of the DNS server and answers given by that server for that DNS server are considered to have authority or are correct. Creating new records To create a new DNS record, right click the zone and select new, followed by the type of DNS record that you want to create. A Record or AAAA This record type creates a mapping from a name to an IP Address. An A record is used for IPv4 and AAAA or Quad A is used for IPV6. When you create an A or AAAA record, you have a tickbox, create associated pointer (PTR) record tickbox. When this tick box is ticked, a reverse lookup record will be created for the A record if a reverse lookup zone exists. A reverse look up zone allows a client to determine the host name given the IP Address. Alias (CNAME) A CNAME record allows the administrator to create a DNS record that effectively redirects the request to a different record. For example, if you had a CNAME record called ftp, you could configure the CName record to point to any other host record on the network. The advantage of this is it can change the CName at any time to point to a different server. The only down side of this approach is that if the client has the old record in their cache, the client will keep using this DNS record until its cache expires. To create a new CName, right click on the zone and select the option, New Alias (CName). In the alias name enter in the name that you want to use. For the fully qualified domain name you can enter in the name or the IP Address. If you enter in the name, that name used does not need to be in the same namespace as the zone that it is created in.

Server 2016 And 2012 R2 - Reverse DNS Zone Creation
Server 2016 And 2012 R2 - Reverse DNS Zone Creation We use our DNS servers for changing domain names into IP addresses. Sometimes we might want to go from IP addresses to domain names. This video shows how to create a reverse DNS zone so that we are able to change IP addresses to domain names. For more visit: http://www.windows10.ninja http://www.2012r2.com Transcript (machine generated so it contains errors) Hello today to you in today's video will have a look at how to set up a reverse lookup sound and DNS. Basically what this is is when we type in name power shall carelessness, eczema, shall we say we Wanna find the IP address staff, a company DNS have all surpassed by us giving Google.com and it turns it into an IP address and reverse look up is the exact opposite. We type in an IP address and we want the DNS server to basically give us back the name of that domain okay as an example, let's have a quick look over here. Okay then S look up okay and then set type equals pointer okay and now we have a server server 005 or even this case 006 has an IP address. Okay, so let's just type in 192.16 8.0 .30 okay, now if we had a reverse look up, set up, it would come back and say its call services are six now, that's not there, so we need to go into DNS manager who do that we open up server manager in the server to the 16 it's click over there. Click over there and then click on that okay in server 2012. The words via start screen or in ways that so we now have this and then this opens up like that. Click on DNS, right click over there DNS manager then basically select the server that you have lots of the different here are those with setup for our demo environment. Okay, so basically now reverse lookup zones, user very simple. Next, make as a primary zone perfect okay secondary zone is like a copy zone, a backup zone stub zone the alligator cheaper version of a copy again next okay. See how you wander zone dinner replicated. Basically, this is a nice idea.the default of the year is quite good. Okay, next okay, each with an IP version 46. In this catering for now. What we do is we type in the first three okay first three bytes 19248168.0 okay, and they will be able to resolve all the others okay. Click next okay only secure updates that is ideal as this active directory and where widely secure. Now that's happily set up okay okay, now we can type in the address that we had before. Handmade finds it okay. Sometimes it may not be instantaneous because this is a start, slowly building up all a pointers okay arms. So basically it. My require and restart a refresh or reload you now refreshes over there reloads over there okay and basically on our servers when they join up to the domain when they login it starts building up so over time. It started populated. Alternatively, if you want you can create pointers okay, it's B31 okay then in the hostname is server 205 okay. Do not take that one. Okay, it's not necessarily down to get assessed okay and they get paid servers. There is a five year given the full name like that, but soldiers are five days, from okay arm hopefully does help.

DNS Split Brain
Split-Brain DNS is when the same DNS name is used for internal and external clients. This video looks at the problems associated with Split-Brain and how it may be configured to get around these problems. The choice of Split-Brain or the alterative whole brain approach is up to the individual administrator to decide which approach is best for the network that they support. Download Handout http://itfreetraining.com/handouts/dns/dnssplitbrain.pdf Network Example If you use the same DNS name for the internal network and the external network, the simplest way to implement this would be to use the same zone data on the internal and external network. The problem with this approach is twofold. Firstly this means that the internal DNS records are now exposed to the internet and a hacker may get this information. Using this information, the hacker can foot print the network and gain a good understanding of how many clients and what types of services you have on the network. The second problem is that internal clients may use different IP addresses to access resources than external clients. For example, the company web site may have an external IP Address but the routing on the network does not correctly route internal clients to the web page. In order for this to occur, the internal clients must use an internal IP Address. The DNS server will not know which IP Address to respond with. Whole Brain DNS The whole brain approach is when different domain names are used for the internal and external network. A common approach is to use .local for internal networks and .com for external networks. Using this approach it is quite easy to understand and set up for the administrator. It does however make it a little more complex for the user and thus you are making a trade off from a simple network to look after to one that is more complicated for the end user to use. Using the whole brain approach means that if a hacker were to gain access to the DNS records in the .com namespace, these DNS records are publicity available anyway so this is not really a security concern. The .local records are used on the internal network and thus a lot harder for a hacker to gain access to these. If the internal DNS server cannot resolve a DNS request, for example it is asked for the IP Address of google.com, this DNS request can be forwarded to the other DNS server which can resolve it. This adds additional security to the network meaning that the internal DNS server does not have to communicate directly with the internet. Split-Brain DNS The best way to implement split-brain is to have two different zone files for the same DNS name. The internal DNS server would hold its own set of DNS records while the external DNS server would hold a different set. This means that if an attacker was to gain access to the external DNS server, they would only be able to gain access to DNS records that are publicity available. Problem with Split-Brain The problem with Split Brain is that depending on how a user accesses the network will determine which resources they will be directed to. The most common example is when the user connects via a VPN connection. When connected via a VPN connect the user will be accessing the network just like they were in the office. If you have resources with the same name, like web server or mail servers, the user may be directed to the wrong service. This can become more complicated when you have companies with different offices and divisions around the world. Making sure the user is directed correctly can become quite difficult. When a user connects using a service like DirectAccess, DirectAccess has the ability to configure rules which will direct the user to resources based on their connection. Although this is possible, it does make it more difficult for the administrator as the rules need to be configured.

Как настроить PTR-запись? | REG.RU Видеосправка
PTR запись — это обратная DNS-запись, связывающая IP-адрес сервера с его каноническим именем (доменом). Эта запись широко используется при фильтрации почты. Если вы хотите, чтобы письма отправленные с вашего сервера благополучно достигали адресатов, минуя папку СПАМ, для сервера необходимо прописать корректную PTR-запись. В значении записи PTR должен стоять домен или поддомен, который резолвится с самого сервера. Например: - в качестве PTR записи вы прописываете поддомен ptr.site.ru (или mail.site.ru или любой другой); - для этого поддомена должна быть прописана «A запись» на IP вашего сервера.   - если вы попробуете пропинговать поддомен при помощи команды ping имя.поддомена, в выводе должен фигурировать IP-адрес вашего сервера. Чтобы прописать  PTR-запись, выполните следующий порядок действий: - перейдите в разделе «Хостинг и услуги» и кликните по необходимой услуге VPS-сервера. - в разделе «Управление услугой» выберите пункт ”Изменить обратную DNS-запись”. - введите имя хоста для обратной записи и нажмите ”Подтвердить изменение обратной DNS-записи” Хочешь больше полезной информации?

Creating DNS Records in Windows 2008
DNS is the most important service in your Active Directory Environment. This standards-based service is used to locate everything from web sites to domain controllers to global catalog servers. If your DNS isn't set up properly, you won't even be able to log on to a Windows domain environment. In this video, Senior Technical Instructor Doug Bassett shows you how to create a variety of DNS records to support your network environment. He shows you how to create SOA, NS, A, CNAME, PTR and SRV records. He provides detailed information on each record, including the usage, optimization and any "gotcha's" associated. If you want to learn more about DNS, including working with Active Directory and ensuring proper configuration, optimization and security, please attend either the Network Infrastructure course or the Active Directory Administration course. We look forward to seeing you soon!

The types of records are A and AAAA records for normal lookups in a IPv4 or IPv6 environment. (Glue record) PTR records for a reverse lookup zone. This is the opposite of DNS. It's IP Address mapping to DNS name. MX records for mail exchanger CNAME for canonical name records. These resolve one name to another name. It's like a nickname for machines. NS records to specify other name servers. SOA records to identify the server in charge of the domain. Providing training videos since last Tuesday. http://www.technoblogical.com Thanks for watching.

DMARC   Overview & Configuration
DMARC (Domain-based Message Authentication, Reporting and Conformance) is an anti-spoofing technology that makes it possible for domain owners to use the Domain Name System (DNS) to inform receiving servers of their DMARC policy, which is how they want those servers to handle messages that claim to be sent from their domain but cannot be authenticated as having actually come from it. In this webinar, we'll introduce you to DMARC, describe its purposes and goals, and explain how it works. Then, we'll show you how to configure MDaemon to use DMARC to verify incoming messages. This webinar focuses specifically on MDaemon's implementation of DMARC, however, for a more technical and comprehensive overview of DMARC, and as a prerequisite for this webinar, we recommend viewing the Video Training series located at www.dmarc.org.
