The common thing between telnetd and netstat is that they are both doing a
gethostbyaddr() to translate an IP address into a hostname (as opposed to a
gethostbyname() that does the reverse).  Since you are using a nameserver,
the problem is almost certainly that you forgot to change the name in the
database for the in-addr.arpa domain that maps addresses to hostnames.
Look in this file for the PTR record with your IP address, and my guess is
that it will have RISCSRV as the hostname.
