The website https://webwork.xula.edu/webwork2 is unreachable. In an nslookup using 126.96.36.199 server, it says non-existent domain.
*** google-public-dns-a.google.com can't find webwork.xula.edu/webwork2: Non-existent domain
This same site is reachable if accessed over a mobile network, but not when connected through local service provider internet service. Although I am able to find a DNS record when using the local service provider DNS server.
Performed a lookup using Google DNS 188.8.131.52 on the site without /webwork2.
> server 184.108.40.206
Default Server: google-public-dns-a.google.com
I'm able to get a non-authoritative answer that way, but the site is unreachable either way. I'm able to ping the DNS servers. Unable to ping the URL or either IP address.
