See rfc2782 for "howto".

Quoting from rfc2782 :
"The format of the SRV RR

   Here is the format of the SRV RR, whose DNS type code is 33:

        _Service._Proto.Name TTL Class SRV Priority Weight Port Target"


And also an example :
$ORIGIN example.com.
      @               SOA server.example.com. root.example.com. (
                          1995032001 3600 3600 604800 86400 )
                      NS  server.example.com.
                      NS  ns1.ip-provider.net.
                      NS  ns2.ip-provider.net.
      ; foobar - use old-slow-box or new-fast-box if either is
      ; available, make three quarters of the logins go to
      ; new-fast-box.
      _foobar._tcp    SRV 0 1 9 old-slow-box.example.com.
                       SRV 0 3 9 new-fast-box.example.com.
      ; if neither old-slow-box or new-fast-box is up, switch to
      ; using the sysdmin's box and the server
                       SRV 1 0 9 sysadmins-box.example.com.
                       SRV 1 0 9 server.example.com.
      server           A   172.30.79.10
      old-slow-box     A   172.30.79.11
      sysadmins-box    A   172.30.79.12
      new-fast-box     A   172.30.79.13
      ; NO other services are supported
      *._tcp          SRV  0 0 0 .
      *._udp          SRV  0 0 0 .
