5 Select a resource record type, and specify the appropriate data:
For an A record you will need to enter the domain name for which you wish to
create an A record. If you are simply defining an A record for your main domain,
then you should leave the available field empty. If you are defining an A record
for a name server then you will need to input the appropriate entry for the given
name server (ie. ns1). Then, you need to enter the appropriate IP address to
which to associate the domain name.
For a NS record, you will need to enter the domain name for which you wish to
create the NS record. If you are defining an NS record for your main domain,
then you will leave the available field blank. Then enter the appropriate name
server name in the field provided. You will need to enter the complete name (i.e.
ns1.mynameserver.com).
For a MX record, you will need to enter the domain for which you are creating
the MX record. For the main domain, you would simply leave the available field
blank. You will then need to enter your mail exchanger, this is the name of the
mail server. If you are running a remote mail server named
'mail.myhostname.com' then you would simply enter 'mail.myhostname.com'
into the field provided. You will then need to set the priority for the mail
exchanger. Select the priority using the drop-down box: 0 is the highest and 50
is the lowest. Keep in mind you would also need to add the appropriate A
record, and/or CNAME if applicable for the remote mail exchange server.
For a CNAME record, you will need to first enter the alias domain name for
which you wish to create the CNAME record. You then need to enter the domain
name within which you want the alias to reside. Any domain name can be
entered. It does not need to reside on the same server.
For a PTR record you will first enter the IP address/mask for which you wish to
define the pointer. Then enter the appropriate domain name for this IP to be
translated to.
For a TXT record, you will be able to enter an arbitrary text string, which could
be a description or an SPF record.
For an SRV record, you will need to enter the service name, protocol name, port
number, and target host. Service and protocol names should start with the
underscore symbol. You can also specify the priority of the target host, and
relative weight (for records with the same priority) in the appropriate fields.
