About IPv4 to IPv6 Conversion
Convert IPv4 addresses to various IPv6 representations including IPv4-mapped, IPv4-compatible, 6to4, and IPv6-translated addresses. Essential for network migration and dual-stack configurations.
Conversion Types
IPv4-mapped (::ffff:a.b.c.d) represents IPv4 hosts in an IPv6 context. IPv4-compatible (::a.b.c.d) was used for automatic tunneling. 6to4 (2002:aabb:ccdd::) enables IPv6 over IPv4 networks.
How to Use
Enter an IPv4 address and the tool will display all available IPv6 conversion formats. Each result can be copied to clipboard.
▶What is an IPv4-mapped IPv6 address?
It's an IPv6 address that represents an IPv4 node, formatted as ::ffff: followed by the IPv4 address. Used by dual-stack systems to handle both protocols.
▶Why are there multiple IPv6 formats?
Different transition mechanisms use different address formats. IPv4-mapped is for dual-stack, 6to4 is for tunneling, and each serves a specific purpose in IPv4-to-IPv6 migration.
▶Can I convert IPv6 back to IPv4?
For IPv4-mapped and IPv4-compatible addresses, yes. The last 32 bits contain the original IPv4 address. Pure IPv6 addresses cannot be converted back to IPv4.
