Love the free DNS.
I’m on Google fi and find that while using cellular internet 220.127.116.11 is inaccessible. However 18.104.22.168 is accessible.
Since this 22.214.171.124 is accessible it’s not really a problem. However Firefox users who set only DNS over https will be frustrated, since it uses a dotted decimal bootstrap address, which in guides typically get set to 126.96.36.199.
Or, I’ve been hacked… Seems a bit paranoid though.
Please advise as to whether you know of ISP level blocking of 188.8.131.52
