IPv4-mapped (dotted)::ffff:192.168.1.1
IPv4-mapped (hex)::ffff:c0a8:0101
Full expanded form0000:0000:0000:0000:0000:ffff:c0a8:0101

Frequently asked questions

What is an IPv4-mapped IPv6 address?
It embeds an IPv4 address inside IPv6 using the ::ffff:0:0/96 prefix, letting IPv6 sockets represent IPv4 endpoints.
What is the 6to4 prefix?
6to4 uses the 2002::/16 prefix with the IPv4 address in the next 32 bits to route IPv6 traffic over IPv4 networks.
