Hi,

What to do if the domain name of one of my webserver, that me and some lab members use for work related stuff, is no longer resolved by our university DNS? When I first noticed it, I could see no resolution at all while now the domain resolves to a wrong IP. The site can be normally reached on any other network so there is no problem on my side I think.

Should I just wait (now more than 24 hours) or should I try anything? I am entitled to complain to our IT even though the issue is only with this not-really-professional FreeDNS subdomain?

EDIT: apparently some automatism marked this domain as malicious (absolutely it is not, not willingly and not compromised) and somehow DNS resolves to CNAME sinkhole.paloaltonetworks.com.

Interesting, thanks. I think this is what it is happening. Feels like I can put whatever DNS server and still end up with an internal one.

You can confirm this as follows. Grab a laptop and:

  • Confirm that on the university internet, 8.8.8.8 resolves the wrong domain.
  • Set up a hotspot from your mobile phone, connect the laptop there, then try again.

If the behaviour is different depending on your network, your uni must be redirecting DNS.
