8.2.1.9.3 IPAddress
The IPAddress condition makes it possible to validate the associated against an IP number and a mask, to determine if the string in the field is an acceptable IPv4 address, see Figure 149.
The format used for IP addresses is n.n.n.n/x, where:
- n is a part of the IP address in the range 0–255
- x is the mask, in the range 1–32
The IP mask can be described exactly, using a wildcard, or using the Classless Inter Domain Routing (CIDR) format.
Some IPv4 examples of the input accepted in this condition are laid out below.
- Exact match: An exact match is to be used when an exact IP address must be compared.
136.0.0.32
- CIDR: Using a CIDR mask that the 8 most significant bits for the address given are used for comparison. In this example, an IP address that starts with 123 it is considered as a match.
123.0.0.32/8
- Wildcard Notation: The IP address can be listed using a wildcard (*), where the wildcard represents any values after its insertion.
136.* is the same as 136.0.0.0/8, 136.225.* is the same as 136.225.0.0/16 and 135.225.10.* is the same as 136.225.10.0/24
