DNS zone records specify zone information for the name-to-address
translations performed by the domain name server. The Name Server (NS)
record for the zone’s name server, and Host (A) records for the FTP server
and the domain (www) are automatically created for you, but you can add
others. You can modify the record information at any time.
Another type of zone record, called an SOA
record, serves a very specific purpose and is described in the topic About SOA
records.
The following table describes the supported DNS record types.
Use this record: |
To specify: |
Name Server (NS) |
The host name of a DNS server that is authoritative for the
domain.
|
Host (A) |
A 32-bit IP
address for forward host-name-to-IP-address
mapping. |
AAAA |
A 128-bit IP
address for forward host-name-to-IP-address mapping. |
Pointer (PTR) |
A host name for a reverse IP-address-to-host
mapping. |
Alias (CNAME) |
A mapping between one host name and another.
This record tells the DNS server that any requests made to
the alias name are to be redirected to the host to which the alias points.
The target host does not have to be within the local domain.
Tip: Create a Host (A) record before you create the alias.
Caution! Do not use
a CNAME alias
record for a name-based domain, or an NS
or MX record.
|
TXT |
Text you want to associate with a host name. You can include
SPF-standard compliant text. |
SRV |
Services available for a domain. |
Mail Exchanger (MX) |
A mail server other than the SMTP
server provided by your service provider. You can specify more than one
external mail server.
