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.com

I 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?


  • You need to wait 72 hours for see it on DNS checks sites such as that. You can check your settings internally and at your registrar. May 29, 2013 at 13:25

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.

  • Dan, Thank you for the info. This is what I needed.

  • You're welcome :-) Always scary stuff when you're making DNS changes to a live site...but if different online tools can see them, visitors can too.
