IPv4-Mapped IPv6 Reference
1. Address Structure
An IPv4-mapped address format is written as ::ffff:w.x.y.z or fully expanded in hex as 0:0:0:0:0:ffff:xxxx:yyyy.
2. Dual-Stack Networking
Used extensively in dual-stack operating systems and socket layers to allow IPv6 applications to transparently handle legacy IPv4 client connections.

Frequently Asked Questions (FAQ)
It is a special IPv6 address format used to represent an IPv4 address within an IPv6-only or dual-stack socket infrastructure, prefixed with
::ffff:.
No. Only IPv4-mapped addresses (matching the
::ffff:0:0/96 prefix) contain embedded IPv4 values that can be cleanly extracted.
Yes. All transformations execute completely client-side in your local browser instance.
