Hola, recientemente registré un dominio en dot.tk. El hosting que uso es 000Webhost.
El host me dice lo siguiente:

Código:

You have chosen to host your own domain, so you must update your nameservers first. Ask your domain provider how to do that, we do not register domains. You will see message 'Your website is up and running!' after visiting your domain once it will start working (usually in 24 hours after nameserver update).
 

You need to point your domain to these nameservers:

dns1.000webhost.com - 64.22.110.162

dns2.000webhost.com - 75.126.210.153
 

We do not provide assistance in updating nameserver because we have not registered your domain. Read this FAQ for information how to update nameservers.
 

If you still don't have idea how to update your nameservers, please click here to setup new account and choose our free subdomain, it will start working immediately.
