Hello,
I am afraid that you are not able to register or transfer a co.nr domain in your account with us. Because this TLD is not supported by our system. You are able to see a list with the domain TLDs which we offer following the link below:
http://freehostia.com/domains.html
In addition you are able only to host a co.nr domain in your hosting account via Control Panel Hosted domain menu which is placed under the Site Management section. After you added the domain to your hosting plan, please content your domain registrar and tell him/her to set our name servers to point to your domain. They are following:
dns1.freehostia.com / IP: 66.40.52.47
dns2.freehostia.com / IP: 66.40.66.152
Please note that the name servers update takes 24 hours in order the name servers to propagate worldwide and your domain name to become operational in your account with us.
If you have any additional questions, please let us know.
Best Regards
WidWool
