Join Timothy Pintello for an in-depth discussion in this video DNS resource records, part of Windows Server 2012 R2: Configure Advanced Network Services.
Now we've talked a bit about DNS. Let's go ahead and talk a bit about DNS Resource Records. There's a wide variety of resource records that are available and are used in DNS. All the different kinds of resource records can be created using the DNS management console. Most of these resource records can also be created in PowerShell. One exception to that is SOA record type. The SOA record type cannot be created using PowerShell. The procedure for setting up records is essentially the same for all the different types of resource records except for the SOA and the NS record types.
To set up a record with the PowerShell you need to use the cmdlet Add-DnsServerResourceRecord for all the resource record types except the SOA record type, which can't be created in PowerShell. You can also use the Set-DnsServerResourceRecord for all the resource records except for SOA also. There are additional Addcmdlets available for the A, AAAA, CName, MX, and PTR records.
You just add the record type that you're trying to create. The A is one of the commonly used resource record types and it is used by IPv4 host address record. In other words a host that has an IPv4 address will use an A record to store that address. Forward lookup then uses that record to translate host names to the IPv4 address that is associated with that host. The AAAA record is just like the A record except that it's for IPv6 host address records.
Again the Forward lookup record will use the AAAA resource record to translate host names to the IPv6 address that matches the host. Another type of commonly used resource record is the CName. CName stands for canonical name record and the canonical name record allows more than one resource record to refer to the same host. The MX record or mail exchanger record, is a record that's used to identify email servers for a domain.
It is possible to have multiple MX records for a domain. You also have the option of setting up an order or precedence inside the MX record. NS or name server record, is another widely used resource type and the NS record identifies a name server for a domain. Again just like with the MX record, you can have multiple NS records in a domain. Next we have the PTR record or the pointer record.
The pointer record is used by reverse lookup and basically what it does is it translates an IP address into a host name. If you remember the A and AAAA records translate a host name to IP, the PTR record translates an IP to a host name. You can use the same PTR record for both IPv4 and IPv6 addresses. Next we have the SOA record. The SOA record stands for start of authority record and it contains a version number record that identifies the version number for a DNS zone.
Finally we have the SRV record. The SRV record is a service record and it's used to identify host name and port number of servers for specified services. So this CP or something like that.
