A

A host address. The `data’ column should contain the IP address (in numbers-and-dots format) associated with the `name’. example: `192.168.1.88’

CNAME

The canonical name for an alias. The `data’ column should contain the real name of the machine specified by `name’. `data’ may be a hostname or an FQDN. example: `porcini.example.com.’ (FQDN) example: `porcini’ (hostname only)

MX

Mail exchange. The `data’ column should contain the hostname or FQDN of a mail server which will accept mail for the host specified by `name’. The `aux’ column should contain a preference for this mail server. Mail transfer agents prefer MX records with lower values in `aux’. example: `ns0.example.com.’ (FQDN) example: `ns0’ (hostname only)

NS

An authoritative nameserver. The `data’ column should contain the hostname or FQDN of a server which should be considered authoritative for the zone listed in `name’. example: `france.example.com.’ (FQDN) example: `france’ (hostname only)

SRV

Server location. Specifies the location of the server(s) for a specific protocol and domain. The `data’ column must contain three space-separated values. The first value is a number specifying the weight for this entry. The second field is a number specifying the port on the target host of this service. The last field is a name specifying the target host. If the target host you specify does not end with a period, the hostname of the current domain will be appended (i.e. adding an SRV target host “bob.cc” for example.com shows up as “bob.cc.example.com.”, but “bob.cc.” will stay as “bob.cc.”). The `aux’ column should contain the priority of this target host. Targets with a lower priority are preferred. For more information, read RFC 2782. example: `0 9 server.example.com.’ (FQDN) example: `0 9 server’ (hostname only)

TXT

A text string. The `data’ column contains a text string that is returned only when a TXT query is issued for the host specified by `name’. example: `This is a string.’
