What is IPv4 to IPv6 Converter?
The IPv4 to IPv6 Converter transforms IPv4 addresses into multiple IPv6 representations including the standard IPv4-mapped notation (::ffff:), the fully expanded 128-bit address, the 6to4 tunnel address (2002::), binary octets, and the 32-bit decimal value. Input validation ensures only valid IPv4 addresses are processed.

Frequently Asked Questions
What is an IPv4-mapped IPv6 address?
It's a way to represent IPv4 addresses within the IPv6 address space using the ::ffff: prefix, enabling compatibility between the two protocols.
What is a 6to4 address?
A 6to4 address uses the 2002:: prefix followed by the IPv4 address in hex, allowing automatic tunneling of IPv6 over IPv4 networks.
