For those interested in more memorable DNS IPs, there is the following:

Just be careful, because TWNIC/Quad101 was subjected to a BGP hijack in 2019[0]

    101.101.101.101 [TWNIC]
    80.80.80.80 [FREENOM][1]
    4.2.2.2 [Level 3]

On IPv6, I like using 2600::1.

Short and easy to remember thanks to the classic 2600 zine (named after the Captain Crunch cereal whistle which emitted the 2600hz tone for payphones). I wonder if someone at Sprint is a fan.

Don't forget 1.1.1.1 and 1.0.0.1 (aka 1.1) [Cloudflare]

Yeah I left that out for a reason. Most geeks know about that. Also 9.9.9.9 is an obvious one. I wanted to point out lesser known/esoteric ones

In China 114.114.114.114 / 114.114.115.115 or 223.5.5.5 / 223.6.6.6 is used.

4.2.2.2 is only for Level 3 customers (now Lumen). You will get mixed results and I believe they have hijacked NXDOMAIN responses for non-customers in the past.
