I’m running an XMPP server and have specified the SRV records
_xmpp-client._tcp
, and_xmpp-server._tcp
.
I often see that people also specify _jabber._tcp
(for example, in Alnitak’s answer), but I can’t find this value in RFC 6120.
What is _jabber._tcp
for? Should I specify it, too?
The _jabber SRV resource record is deprecated. Don't worry about it unless you want to support old, legacy clients.

SRV records are described in RFC 2782. They are DNS records that applications can use to locate services on the network.
