When making changes to DNS records it can take time for these to propagate fully. This means waiting for DNS providers to recognise the change globally and different record types can take longer to update than others.
If you have changed the authoritative nameservers with your current domain registrar, it may take up to 48 hours to be reflected globally. This is not something that Vercel has any control over, and for certain registrars, this can be slower.
Once nameservers have been changed, you may wish to check the progress of the propagation. There are many third-party tools that do this, such as DNS Checker and DNS Map - these show the state of your DNS records in different regions of the world.
You can also use the terminal to check the nameservers for your domain according by specific DNS providers, some examples are found below:
1dig @22.214.171.124 +short NS vercel.com
1dig @126.96.36.199 +short NS vercel.com
1dig @ns1.vercel-dns.com +short NS vercel.com
The following records should propagate in a few minutes or seconds:
Therefore, you can query these records usually within minutes after adding them:
You can check the propagation progress of these records for your domain with third-party tools like DNS Checker and DNS Map in the same way you can for nameservers.
