ssh to IP literal

[Victor Sudakov]

Colleagues,

Is it a bad thing to use IP literals as Kerberos principals? 
However, I am curious. When I try to "ssh user at 10.14.134.5", a very
strange ticket is being requested from the KDC:

2010-12-13T09:14:15 TGS-REQ sudakov at SIBPTUS.TOMSK.RU from IPv4:10.14.134.125 for krbtgt/14.134.5 at SIBPTUS.TOMSK.RU
2010-12-13T09:14:15 Server not found in database: krbtgt/14.134.5 at SIBPTUS.TOMSK.RU: No such entry in the database
2010-12-13T09:14:15 Failed building TGS-REP to IPv4:10.14.134.125

What exactly is "krbtgt/14.134.5" ? Why only the last 3 octets of the
address?

The implementation is Heimdal 1.1.0 from the FreeBSD base system.
