Nslookup requires that the nameserver be able to look up its
own reverse address. This lookup is failing. I suggest that
you investigate by checking that the servers for
168.192.in-addr.arpa and/or 0.168.192.in-addr.arpa is loading
the zones properly. Next ensure that there is a PTR record
for 128.0.168.192.in-addr.arpa.

Add an entry to the dnsalias.com zone.
