Hi the problem is when you do an nslookup on xxx.xx.xxx.xxx
nslookup expects that that ip address will reverse resolve into a domain name
I assume that the ip address are your ISP
you need to asked them to add some pointers for reverse lookups as you can't do that as that netblock is probably under there control
you could ask then to add say

xxx.xx.xxx.xxx-ADDR.ARPA    PTR=ns.yourdomain.com
and
yyy.yyy.yyy.yyyy-ADDR.ARPA    PTR=ns2.yourdomain.com

and that will fix that
