: Setting up VPS: How to configure name servers So I got a VPS set up (LAMP) and have transfered a couple of sites over. Now I want to point my domain names from the old host to the new

@Gail5422790

I just went through this a bit myself(different circumstances/providers/etc), but the checklist:


Make sure you are updating the Serial Number. Since you noted you are hosting the DNS from your VPS, you will need to make sure this is updating.
Make sure your nameserver is registered with your registrar and not just in your dns configs. Just adding ns1.xyz.com and ns2.xyz.com to your dns records won't tell the registrar to respect it as a nameserver. There should be an option to add or register a new nameserver.
ns1 and ns2 pointing to the same host... some interfaces will reject this.
"* CNAME to park.planetdomain.com" might be catching stuff.
Perform a local lookup check on your nameserver to make sure that your configs are correct and serving what you expect them to be serving out.


While most updates happen quickly, in as little as an hour. I've seen some take more than a day or two.

It sounds like your domain records have not propagated yet. This means that the domain name servers around the world that store a record of your domain information haven't updated with the latest details, so they are still 'sending' visitors to your old server.

The solution is to wait. It can take between 0 and 48 hours for domain name changes to update around the world. (More here.)

Lowering the TTL to one hour won't immediately affect the speed of this update – if your previous TTL was 12 hours, it will take 12 hours before the new TTL of one hour takes effect. You'll also have to wait whatever time your previous TTL specified before the nameserver changes take effect.

To check whether global nameservers have updated with your latest domain information, you can do a DNS propagation check:


Visit www.whatsmydns.net/ Type your domain name into the box on that page.
Select "NS" from the drop down (instead of "A")
Click "Search"


You'll see a list of nameservers records from around the world that look like this:



If you see the old nameservers next to your domain for some of the locations, it means that your change hasn't propagated around the Internet yet and you'll have to wait longer.

If you see the new nameservers next to your domain for all locations but you're still seeing the data at the old server when you visit your domain, then your computer could be caching the old domain information. You can flush your local DNS cache and revisit your site to force your local records to update.

You can also confirm what the nameservers appear to be from your own location by using the dig tool in the command line (installed by default on Mac/Linux, but available to download for Windows):

dig NS stackexchange.com
