Hi DNSAU, I have been given 2 DNS which are ns1.xternal-host.us & ns2.xternal-host.us from my webhost but there are using the same ipaddress which is 209.97.221.20. So, what can i do next and able to use your free domain name (.com.ru)? Do i need to use another secondary DNS service provider likes xname or zoneedit? Pls advise....

Thank you. ;)

Yes you can do this, but you will have to get your host to include the secondary nameserver in the domain's primary zone file. A lot of hosts won't do this, but give it a try, otherwise search for a host that has nameservers in different C block subnets.
