Free DNS resolution service called 1.1.1.1.2.1 was created by APNIC and Cloudflare, who own the 1..1 address, and who will use their network to host the DNS service. The new service promises to never write the IP address of a client to disk and to wipe all transaction logs within 24 hours. CloudFlare claims that they are now 28% faster than any other DNS service as rated by DNSPerf. 1.2: 1.3:1.4: 1:1.4:1 is a free DNS resolution.
