[JDEV] Jabber 1.4: using IP instead of FQN

[David Waite]

Generally, DNS names should be used.

Specifically,  Jabberd doesn't use DNS internally for identification, so if the name doesn't match what it is
expecting things will not work.

So when you do <stream:stream to='208.245.212.100' ...> , it doesn't  find the jabber session manager specified
by
<service id="jabber.org">

Also keep in mind that the 'jabber.org' and '208.245.212.100' cannot be the same thing within JSM - if one
person connected as test at 208.245.212.100, they will be on a different virtual server than test at jabber.org.
