I will put this with an example.Suppose to add the SRV record that looks like:
_http._tcp.example.com 86400 IN SRV 0 5 5060 httpserver.example.com.
that points to a server named
listening on TCP port 80 for HTTP protocol connections. The priority given here is 0, and the weight is 5, specify the following in the form fields:
_http._tcp in the Name field.
86400 in the TTL field
select SRV from the Type drop-down menu.
Type 0 5 5060 httpserver.example.com. into the Value field.
Revert back if you need further help.
