IPv4 to IPv6 converter

Enter an IPv4 address to see the mapped IPv6 representation used in dual-stack sockets. FlashKit does not assign you an IPv6 prefix.

Mapping is not the same as running native IPv6 on a public site.

How to Use

  1. Paste a valid IPv4 address.
  2. Copy the :ffff: form if a dual-stack ACL needs it.
  3. Use the CIDR calculator for real subnet math.
  4. Ask your host for a native IPv6 assignment if you need to serve AAAA.

Key Features

  • IPv4-mapped IPv6 notation
  • Local only
  • No ISP API
  • Pairs with CIDR and IP lookup
