So you've changed something in your DNS Domain. Is it already valid in "The Internet"?

Ask several nameservers at once with digger:

#!/bin/bash
 
# ask several nameservers
 
# usage (same options like dig):
# digger www.example.com
# digger -t aaaa www.example.com
# digger -t ns example.com
 
name=$@
 
cloudflare="1.1.1.1"
google="8.8.8.8"
# this is empty, if you don't use network manager on your machine
networkmanager_local=$(nmcli dev show 2>/dev/null | awk '/DNS/ {print $2}')
# enter your own nameserver ips (use a space as seperator)
myown=""
 
nameserverliste="$cloudflare $google $networkmanager_local $myown"
 
for n in $nameserverliste; do
    echo "dig +short $name @$n"
    dig +short $name @$n
    echo
done
