Transferring Existing Domain
To change your Name Servers, log into your Tucows reseller domain management interface, or http://manage.opensrs.net. Then click on the Name Servers link.
The nameservers for your hosting account are:
Always add the new nameserver first using Adding New Name Servers
Note: You only have to add the hostname. The IP is handled automatically.
Then, you can remove the old name server by clicking the remove check box to the right and clicking Save Configuration . Please note this action does not delete the name server entry and instead removes it from this domain only.
This procedure assumes that the nameservers in question are valid registered Internet nameservers. Some registries such as .us, .info, .biz, .name, .org and .cc maintain their own databases of registered, valid name servers, rather then going by the VeriSign .COM/.NET Registry database. If you are receiving unable to verify existance of name server error messages, it is likely due to the name server not being found in their database. You can add your name servers to the various registries through the Add Nameserver to All Foreign Registries link in the resellers interface. If you are not an Tucows Reseller please contact your reseller to have the name servers added.
Please note that the name servers IP addresses will only show up when you use a name server based on the same TLD. For example, the IP address will show up when you use a .org name server (ex: ns1.example.org) on a .org domain (ex: tucows.org). Not displaying the IP has no effect on the resolution of the domain name; it is strictly cosmetic.
