Final answer:
The Cidrmatch(X,Y) function is used in networking to check if an IP address (X) is within a CIDR block (Y), returning a boolean true or false accordingly. It aids in network configuration and security by validating IP ranges.
Step-by-step explanation:
The Cidrmatch(X,Y) function is typically used in the context of networking and computer science. It is designed to determine if an IP address (X) falls within a particular CIDR block (Y). CIDR stands for Classless Inter-Domain Routing, which is a method for allocating IP addresses and routing internet protocol packets. The function returns a boolean value; it will return true if the IP address is within the range defined by the CIDR block, and false otherwise. This is useful for network configuration and security purposes, ensuring that access is granted or restricted appropriately based on IP address ranges.
For example, if you run Cidrmatch('192.168.1.1', '192.168.1.0/24'), the function will return true because the IP address '192.168.1.1' falls within the '192.168.1.0/24' subnet.
