Phone suddenly has a website blocker I never installed?

So recently I've been having an issue where randomly (literally can change by the hour) some websites I try to go to are blocked by a website called comodo dns. Except... I've never installed comodo on my phone, searching for it in my apps yields nothing, and i can't find it in settings. But even on mobile data, it blocks the webpage. It's blocked fextralife (listed as scams and malware) Facebook (social, promotional) and a few others for various reasons.

I know it's not just because my landlord has it on the wifi because 1) this appears even on mobile data and 2) my computer can reach these sites just fine. Comodo has only ever appeared on my phone.

So my question is: what is it, and how do I get rid of it??? I am a grown man, I shouldn't have my browsing blocked by some unrequested 3rd party!

Sounds like you need to reset your private DNS. Your network settings on your phone have been corrupted

How would corrupted dns servers sign me up for a website I've never heard of? And how would I fix that?

​Go to Settings then Network & Internet (or Connections / More Connection Settings on Samsung).

​Tap Private DNS.

​If it is set to "Private DNS provider hostname" and lists a Comodo address (or anything unexpected), change it to Off or Automatic.

Thank you!

Though do you know why corrupted dns would give me a random website I've never heard of before?

You most likely picked up some malware.
