Usage Examples

See the following sample queries where isSubnetOf is used in different parts of the query.

SELECT isSubnetOf('192.168.0.1/24', '192.168.0.225') 
AS result
FROM myTable;
---> returns true

SELECT isSubnetOf('1.2.3.128/26', '1.2.5.1') 
AS result
FROM myTable;
---> returns false

SELECT isSubnetOf('2001:4800:7825:103::/64', '2001:4800:7825:103::2050')
