The cidrmatch function is used to determine if a given IP address falls within a specified CIDR (Classless Inter-Domain Routing) subnet. When the function is executed and the IP address does indeed belong to the specified subnet, it returns a value of TRUE. This indicates a successful match between the IP address and the CIDR range.

Understanding how CIDR notation works is crucial for interpreting this function. CIDR is represented as an IP address followed by a slash and a number (e.g., 192.168.1.0/24). This notation specifies the network portion and the number of bits in the subnet mask. When you use cidrmatch to check if, for example, the IP address 192.168.1.15 belongs to the 192.168.1.0/24 subnet, the function evaluates whether this address is indeed part of that range and returns TRUE when the evaluation is positive.

In contrast, returning FALSE would imply the IP does not belong to that CIDR range, NULL would indicate a lack of valid input or a failure in matching, and 0 does not represent a logical outcome for this function in the context of matching CIDR with an IP address. Thus, the correct answer
