Why convert an IP address to decimal?

Storing IP addresses as a single integer in a database makes range queries (e.g., 'is this IP within this range?') much faster and simpler than comparing dotted-decimal strings.

Does this work for IPv6?

No, this calculator is for IPv4 addresses only, which fit into a 32-bit integer. IPv6 addresses are 128 bits and require a different representation.

IP to Decimal Calculator

Convert a dotted-decimal IPv4 address into its equivalent 32-bit unsigned decimal integer, useful for database storage, IP range comparisons, and low-level network programming.
