dns problem ask for help

edited May 2022 in General Discussions

my nameserver was set to
ns1.unaux.com and ns2
but I couldn't resolve the domain at local.
neither using "nslookup - ns1.unaux.com"
So is there any wrong with my setting or something wrong by online system ?
domain: henanyinhang.com
I know the server ip for it worked at first and the website works well by setting ip to the hosts file.

ps. what's the relationship between unaux and profreehost?
I don't know the difference between ns1.unaux.com & ns1.freehosting.com

Thanks for help. :)
