Description Author(s) See Also
PostgreSQL has built-in support for IP address and CIDR types but the ip4r https://github.com/RhodiumToad/ip4r extension is much faster. Tools are provided to create CIDR lookup and IP address source tables and perform IP address in CIDR queries. Documentation on how to setup macOS with PostgreSQL and ip4r is also provided.
