IP to Number Converter

Converts IPv4 addresses to and from their 32-bit integer representation using BigInt for full unsigned 32-bit range. Two modes are available: IP to Number (default, with 192.168.1.1 preloaded) and Number to IP (preloaded with 3232235777). Each conversion also shows the hexadecimal, octal, and binary forms of the number.

1. Pick the mode with the IP to Number / Number to IP toggle buttons. 2. Enter an IPv4 address (e.g. 192.168.1.1) or a decimal/hex/octal number in the input. 3. Click Convert (or press Enter). The five output rows appear, each with its own Copy button. 4. Invalid input clears the result and shows a red error message.

When converting a number to an IP, the input may be a plain decimal, a 0x-prefixed hexadecimal, or a 0o-prefixed octal value (prefixes are stripped before parsing). Values must be in the range 0 to 4294967295 inclusive; anything outside that range is rejected as invalid. The binary output is always padded to 32 bits.
