Frequently asked questions

What is IPv4-mapped IPv6?

It is the ::ffff:0:0/96 format that embeds IPv4 inside an IPv6 address. It is used to represent IPv4 connections on IPv6 sockets.

What is 6to4 notation?

It is an IPv6 range (2002:IPv4::/48) for 6to4 tunneling, made by placing the IPv4 address into the 2002::/16 prefix.

Are the entered values sent to a server?

No. All conversion happens only inside your browser, and the values are never sent to or stored on any server.
