Um, thats going to be a problem for some people. There has been widespread use of 22.214.171.124 for wireless gateways/login pages, for sync links between firewall and many other things. You don’t have to use this DNS of course but the address has been used for internal purposes for many years.
Cloudflare’s mission is to help build a better Internet and today we are releasing our DNS resolver, 126.96.36.199 – a recursive DNS service. With this offering, we’re fixing the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. The DNS resolver, 188.8.131.52, is available publicly for everyone to use – it is the first consumer-focused service Cloudflare has ever released.
For IPv6, we have chosen 2606:4700:4700::1111 and 2606:4700:4700::1001 for our service. It’s not as easy to get cool IPv6 addresses; however, we’ve picked an address that only uses digits.

Tom Hollingsworth blogged about the problems:
As it turns out, 1/8 is a pretty bad address space for two reasons. 18.104.22.168 and 22.214.171.124. These two addresses are responsible for most of the inadvertent announcements in the entire 1/8 space. 126.96.36.199 is easy to figure out. It’s the most common example IP address given when talking about something. Don’t believe me? Google is your friend. Instead of using 192.0.2.0/24 like we should be using, we instead use the most common PIN, password, and luggage combination in the world. But, at least 188.8.131.52 makes sense.
