1.1.1 IP address

The Switch supports Class A, B, C, and D IP addresses. Class D addresses are used by routing protocols for multicast. Depending on the routing protocol being used, addresses defined in accordance with Classless Inter-Domain Routing (CIDR) are also supported. The following figure shows the format of an IP address.

Figure 1-1 IP Address Formats

Note that in a network broadcast address or subnetwork broadcast address, the host ID is binary and consists of all 0s or all 1s. You can select which type of host ID you want to use in the configuration for each interface. For details about the interfaces, see 1.2.2 IP Addressing Units.

The IP addresses in the following ranges can be assigned to the Switch:

• Network IDs

  The following network IDs are allowed:

  • Class A:1.x.x.x~126.x.x.x

  • Class B:128.1.x.x~191.254.x.x

  • Class C:192.0.1.x~223.255.254.x (x=host ID)

• Host IDs

  The following host IDs are allowed:

  • Class A:y.0.0.1~y.255.255.254

  • Class B:y.y.0.1~y.y.255.254

  • Class C:y.y.y.1~y.y.y.254 (y=net ID)
