Subnet Contains IP

Subnet Contains IP Analyzer​

The subnetContainsIP analyzer checks if a given IP address falls within a given subnet (CIDR range). This is useful for validating network configurations and ensuring IP addresses are within expected ranges.

Parameters​

cidr (Required)​

The subnet range to check against. The format must be "x.x.x.x/y", with an IPv4 network and y being a CIDR mask between 1 and 32.

ip (Required)​

The IPv4 address to check. Must be in the format "x.x.x.x".

Outcomes​

The analyzer supports the following conditions:

  • true: Indicates that the IP address is within the specified subnet range
  • false: Indicates that the IP address is not within the specified subnet range
