The public Domain Name System (DNS) resolver landscape has historically been dominated by a few well-known anycast addresses, most notably 8.8.8.8 (Google) and 1.1.1.1 (Cloudflare).

3.3.3.3 is a public DNS resolver IP address — a server you can point your device or network to for domain name lookups (translating domain names like example.com into IP addresses). The public Domain Name System (DNS) resolver landscape
Although Level 3's public DNS service using 3.3.3.3 is no longer actively maintained, the IP address remains an interesting footnote in the history of the internet. Today, some network administrators and enthusiasts still use 3.3.3.3 as a DNS server, often out of nostalgia or curiosity. We conclude that while 3
