The notation "198.51.100.0/24" represents a specific range of IP addresses used in computer networking. The "/24" indicates that the first 24 bits of the address are fixed, meaning it can accommodate 256 unique addresses, from 198.51.100.0 to 198.51.100.255. This range is often used for documentation and examples, ensuring that real IP addresses are not mistakenly used. This address falls within the IPv4 format, which is the most common type of IP address. The Internet Assigned Numbers Authority (IANA) has designated this range as a "TEST-NET" address, meaning it is reserved for use in examples and should not be routed on the public internet.
