I'm always pleased to find a new small utility or tool along the way. Today I found the
hostcommand for verifying that the dns servers that I'm hitting from my house have the updated name servers I just adjusted with my domain registrar. It's an alternative to
nslookup, and gives some really useful information.
For my needs, the following did the trick
host -t NS getcalm.io
-t NSpiece tells host to query for name servers, which was just the piece I needed. And yes, I was pleased to find that the new name servers had already propagated.
getcalm.io name server ns3.digitalocean.com.
getcalm.io name server ns1.digitalocean.com.
getcalm.io name server ns2.digitalocean.com.
