CloudFlare's name servers are named after common 2- to 4-letter names such as Bob and Lola. The company initially used standard format domain names like dns1.cloudflare.com, but users tried to be clever by adding more domains, which failed verification. To resolve this issue, they created unique combinations of name server names using a list of one hundred common names. They also commissioned an artist to draw representations of the 100 name servers as ninjas and later added "Woz" in honor of Apple co-founder Steve Wozniak. The name server names are not related, but they reference potentially hundreds of servers running in all of CloudFlare's global data centers.
