Is 1.1.1.1 a Public IP?

The answer is a resounding yes. 1.1.1.1 is a publicly routable IP address, meaning it’s accessible from anywhere on the internet. Assigned to the Asia Pacific Network Information Centre (APNIC) in 2010, this address isn’t confined to a local network; its global accessibility is fundamental to its function.

Unlike private IP addresses, which are used within a home or corporate network and aren’t directly reachable from the wider internet, 1.1.1.1 can be traced across the network. This public nature is critical to its role as a widely used DNS resolver. A DNS resolver translates human-readable domain names (like google.com) into machine-readable IP addresses, enabling us to access websites. For a service like this to function, the IP address must be globally reachable. Successfully verifying the traceroute of 1.1.1.1 clearly demonstrates its public status and unrestricted routing capabilities. This public accessibility is the very reason why it’s functional as a public service.
