Immutable IP Address Library For PHP

There are two primary immutable IP address libraries for PHP: darsyn/ip and mlocati/ip-lib. darsyn/ip focuses on immutable value objects for IP addresses with helper methods for ranges and checks. mlocati/ip-lib handles IPv4, IPv6, and IP ranges, supporting CIDR and pattern formats, with database integration for efficient range checks. Choose the library based on your specific needs for immutability, IP ranges, and database integration.
