GigaX2008EX L2 Managed Switch User Manual 6 IP Addresses, Network Masks, and Subnets 6.1 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 Appendix 6. IP addresses, the Internetʼs version of telephone numbers, are used to identify individual nodes (computers or devices) on the Internet.
PAGE 61
GigaX2008EX 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.
PAGE 62
GigaX2008EX L2 Managed Switch User Manual 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. 11111111.
