The SQL type inet describes IPv4 network addresses. The inet module contains a collection of functions that operate on IPv4 addresses. The most relevant functions are the `containment' functions that deal with subnet masks.
| Description | |
|---|---|
| sys.broadcast(p inet) returns inet | |
| sys.host(p inet) returns clob | |
| sys.masklen(p inet) returns int | |
| sys.setmasklen(p inet, mask int) returns inet | |
| sys.netmask(p inet) returns inet | |
| sys.hostmask(p inet) returns inet | |
| sys.network(p inet) returns inet | |
| sys.text(p inet) returns clob | |
| sys.abbrev(p inet) returns clob | |
| sys."left_shift"(i1 inet, i2 inet) returns boolean | |
| sys."right_shift"(i1 inet, i2 inet) returns boolean | |
| sys."left_shift_assign"(i1 inet, i2 inet) returns boolean | |
| sys."right_shift_assign"(i1 inet, i2 inet) returns boolean |
The functionality of this module is greatly inspired by the PostgreSQL inet atom. It should be extended to also support IPv6.
