65.2. Built-in Operator Classes
The core PostgreSQL distribution includes the GiST operator classes shown in Table 65.1 . (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);
