IPv4 to IPv6 Converter
Show the mapped and 6to4 IPv6 forms of an IPv4 address.
IPv4 addresses in IPv6 clothing
IPv6 can carry IPv4 addresses in several standard notations, which is handy when you are debugging dual-stack systems or reading logs that mix the two. This tool shows those forms for any IPv4 address.
The address 192.168.1.1 becomes the mapped form ::ffff:c0a8:0101, the readable ::ffff:192.168.1.1, and the 6to4 prefix 2002:c0a8:0101::. Each is the conventional representation for its purpose.

What is an IPv4-mapped address?
An IPv6 address that embeds an IPv4 address, written with an ffff prefix, used when IPv6 software handles IPv4 traffic.
Is this a real translation?
It shows the standard representations. Actual connectivity still depends on the network supporting the relevant transition mechanism.
