IP Functions

Description

The IPv4 function can use an IPv4 address in dotted decimal notation (example: 192.168.0.1) or an IP address in integer format (example: 3232235521). The subnet parameter is an IPv4 subnet in CIDR notation (example: 192.168.0.0/16).

IP Function Statements

Examples

IPV4_MATCH(address, subnet)

If address belongs to subnet, true is returned. Otherwise, false is returned. If address is not a valid IPv4 address, false is returned. This function is more efficient if address is an integer rather than a string.

1. Example field

   Ipv4: 192.168.1.18

2. Query and analysis statement

   select IPV4,IPV4_MATCH(Ipv4, '192.168.0.0/16')

3. Query and analysis result

   Table 1 Query and analysis result

   IPV4	EXPR$1
   192.168.1.18	true

IPV4_PARSE(address)/IPV4_STRINGIFY(address)

Parses address into an integer IPv4 address. If address is a valid IPv4 address, it can be parsed. If address is not a valid IPv4 address, null is returned.

1. Example field

   Ipv4: 192.168.0.1

   Num: 3232235521

2. Query and analysis statement

   select  IPV4_PARSE(Ipv4), IPV4_STRINGIFY(Num)

3. Query and analysis result

   Table 2 Query and analysis result

   EXPR$0	EXPR$1
   -1062731775	192.168.0.1
