Convert IPv4 and IPv6 addresses to and from integer, hex, binary and octal, and get the IPv4-mapped IPv6 form. The input format is detected for you.
How to use the IP Address Converter
- Type or paste an address or number: 192.168.1.1, 3232235777, 0xC0A80101, 0b1100..., 2001:db8::1 or a large IPv6 integer.
- Leave Input format on Auto-detect, or pick a format if the input is ambiguous, such as hex digits with no letters.
- Every other representation appears below at once. Copy a single value or copy them all.

Frequently asked questions
How does auto-detect decide between IPv4 and IPv6?
Anything with a colon is IPv6 and anything with dots is IPv4. Plain numbers up to 4,294,967,295 are IPv4 and larger ones are IPv6. Hex longer than 8 digits, or binary longer than 32 digits, is treated as IPv6.
Is a number like 12345678 hex or decimal?
Digits alone are read as decimal. Add 0x in front, or set Input format to Hexadecimal, to read it as hex. Input containing a to f is read as hex automatically.
Why would I convert an IP address to an integer?
Databases often store addresses as integers because they are compact and easy to compare, so range checks become simple number comparisons. Some logs and APIs also report addresses this way.
What is an IPv4-mapped IPv6 address?
It is how a dual-stack system shows an IPv4 peer on an IPv6 socket: ::ffff: followed by the IPv4 address, for example ::ffff:192.168.1.1. It is the same 32 bits with a fixed 96-bit prefix.
What is dotted octal?
Each octet is written in base 8 with a leading 0, so 192.168.1.1 becomes 0300.0250.01.01. Many classic parsers accept this, which is why leading zeros in addresses can be dangerous.
