Re: One of my domains is using external name servers. What does this mean?
That means you manage your DNS with a different provider (DNS connects the domain name with it's services like hosting and email). So for example if you register a domain name with GoDaddy but set the nameservers to a different hosting company you would manage your DNS with that host. You can switch back to the default nameservers if you want to manage the DNS with GoDaddy, note you would need all the records for your website, email, etc here as anything setup in the DNS from your hosting account would no longer be active.
