dns glue or duct tape??

Friday, 14 May 2021

Hi folks

With help from this list I recently updated my DNS configuration to provide
for a primary and secondary DNS server where the primary DNS server is my
host inside my domain and the secondary server is provided by AT&T

I discovered that the secondary server on file with my registrar  was wrong
so I got the right data  and they claim to have created a glue record but
I'm still getting that host is not responding

*primary dns ws.linuxlighthouse.com <http://ws.linuxlighthouse.com>*
*Secondary server ns2.swbell.net <http://ns2.swbell.net>*

would some kind soul direct me to a coherent glue (or duct tape) record
test?

also, given some domain name how do you know which top level domain name
servers should be the first set that you query to locate your domain in
question??
