The core PostgreSQL distribution includes the GiST operator classes shown in Table 56-1 . (Some of the optional modules described in Appendix F provide additional GiST operator classes.)

For historical reasons, the inet_ops operator class is not the default class for types inet and cidr . To use it, mention the class name in CREATE INDEX , for example
CREATE INDEX ON my_table USING gist (my_inet_column inet_ops);
