Extensions
The `inet` extension defines the `INET` data type for storing [IPv4](https://en.wikipedia.org/wiki/Internet_Protocol_version_4) and [IPv6](https://en.wikipedia.org/wiki/IPv6) Internet addresses. It supports the [CIDR notation](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing#CIDR_notation) for subnet masks (e.g., `198.51.100.0/22`, `2001:db8:3c4d::/48`).
