I recently moved my website to a VPS solution and in doing so was instructed to set up two custom nameservers with my domain registrar: ns1.mydomainname.com and ns2.mydomainname.comI followed the instructions but I am not sure how to tell if they are actually active. I tried checking on http://www.whatsmydns.net/ and it resolves to the current IP for my active site.My point is to make sure the nameservers are 'live' before I make the switch. What is the recommended way to confirm a custom nameserver is valid?Thanks.
How can I tell when a custom name server is active?
nameserver
Once the nameservers appear in Internic's WHOIS http://www.internic.net/whois.html, it can take up to a few hours for DNS record changes for a domain to propagate throughout the Internet to DNS servers.You can Google online NSLookup tools to verify that the nameservers resolve and are pointing to the correct IP address. Within a 24 hour period of confirming that, you should be safe to switch to the new nameservers.
