Seamlessly map legacy IPv4 addresses into IPv6 environments. Instantly generate IPv4-Mapped IPv6 addresses, 6to4 prefixes, and IPv4-Compatible formats.
| IPv4-Mapped IPv6 Address (Most Common) | |
|---|---|
| Dot-Decimal Notation | ::ffff:192.168.1.1 |
| Hexadecimal Notation | ::ffff:c0a8:0101 |
| 6to4 Transition Mechanism | |
| 6to4 Prefix (/48) | 2002:c0a8:0101::/48 |
| IPv4-Compatible IPv6 Address (Deprecated) | |
| Dot-Decimal Notation | ::192.168.1.1 |
| Hexadecimal Notation | ::c0a8:0101 |
As the internet transitions from IPv4 to IPv6, devices operating on pure IPv6 networks often still need to communicate with legacy IPv4 systems. To facilitate this, network engineers use specific transition mechanisms and addressing formats to embed an IPv4 address directly inside an IPv6 address.
ffff), and ends with the 32-bit IPv4 address. Format: ::ffff:192.168.1.1. This is heavily used in dual-stack software applications and databases.
/48 IPv6 prefix by combining the prefix 2002::/16 with the 32-bit public IPv4 address converted to hexadecimal.
::192.168.1.1). This method has been officially deprecated by the IETF (RFC 4291) but is still referenced in older networking textbooks.
