IPv4 Address Converter

How to use this IPv4 address converter

  1. Type any IPv4 address (like 192.168.1.1).
  2. See it instantly as a 32-bit decimal number, binary, hex, and IPv6-mapped notation.
  3. Useful for low-level networking, firewall rules, or understanding IPv6 transition.

What is an IPv4-mapped IPv6 address?

It's a way to represent an IPv4 address within the IPv6 address space, using the format ::ffff:a.b.c.d, allowing IPv6-only systems to communicate with IPv4 hosts during the ongoing transition between the two standards.

Why convert an IP to a single decimal number?

Databases and some networking code store IP addresses as a single 32-bit integer for efficient range comparisons and storage, instead of the human-readable dotted format.

What does the binary format tell me?

It shows exactly which bits are set, which is useful for understanding subnet masks and manually verifying subnet calculations bit by bit.
