It's always DNS, should I complain?
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.
You're viewing a single thread.
Why are you using a crappy uni DNS? Why not 1.1.1.1 or OpenDNS or even Google's 8.8.8.8?
That doesn't help when you run the server and other people have to access your website.
Well, the main point is I would need to manually change this for tens of pcs and its not my job, moreover other people should to the same on theirs. Nevertheless, I just tried 8.8.8.8 on a couple of PCs and I have the same issue! It appears that my DNS setting is irrelevant as it is overwritten down the chain, the only way I can reach the site is put the line in etc/hosts. Could it be?
Yes, your uni might intercept communication on port 53 and reroute it to their DNS servers. It's possible.
In that case just use a DNS that listens on a different port
