GigaX2024B L2 Managed Switch User Manual 6 IP Addresses, network masks, and subnets 6.1 Note IP addresses This section pertains only to IP addresses for IPv4 (version 4 of the Internet Protocol). IPv6 addresses are not covered. This section assumes basic knowledge of binary numbers, bits, and bytes. For details on this subject, see Chapter 8. IP addresses, the Internetʼs version of telephone numbers, are used to identify individual nodes (computers or devices) on the Internet.
GigaX2024B L2 Managed Switch User Manual Following are examples of valid IP addresses: Class A: 10.30.6.125 (network = 10, host = 30.6.125) Class B: 129.88.16.49 (network = 129.88, host = 16.49) Class C: 192.60.201.11 (network = 192.60.201, host = 11) 6.1.2 Network classes The three commonly used network classes are A, B, and C. (There is also a class D but it has a special use beyond the scope of this discussion.) These classes have different uses and characteristics.
GigaX2024B L2 Managed Switch User Manual Subnet masks are used to define subnets (what you get after dividing a network into smaller pieces). A subnetʼs network ID is created by “borrowing” one or more bits from the host ID portion of the address. The subnet mask identifies these host ID bits. For example, consider a class C network 192.168.1. To split this into two subnets, you would use the subnet mask: 255.255.255.128 Itʼs easier to see whatʼs happening if we write this in binary: 11111111. 11111111.
