IP Address Assignment For IP address configuration, there are three parameters needed to be filled in. They are IP address, Subnet Mask, Default Gateway and DNS. IP address: The address of the network device in the network is used for internetworking communication. Its address structure is shown Fig. 2-8.
24 Port Gigabit Ethernet PoE Switch – User Manual Page 12 of 72 ________________________________________________________________________ Class C: IP address range between 192.0.0.0 and 223.255.255.255. Each class C network has a 24-bit network prefix followed 8-bit host address. There are 2,097,152 (2^21)/24 networks able to be defined with a maximum of 254 (2^8 –2) hosts per network.
24 Port Gigabit Ethernet PoE Switch – User Manual Page 13 of 72 ________________________________________________________________________ Not all IP address is available in the sub-netted network. Two special addresses are reserved. They are the addresses with all zero’s and all one’s host number. For example, an IP address 128.1.2.128, what IP address reserved will be looked like? All 0s mean the network itself, and all 1s mean IP broadcast. 128.1.2.128/25 Network Subnet 10000000.00000001.00000010.
24 Port Gigabit Ethernet PoE Switch – User Manual Page 14 of 72 ________________________________________________________________________ This means it is a small network accommodating a maximum of 15 nodes in the network. Default gateway: For the routed packet, if the destination is not in the routing table, all the traffic is put into the device with the designated IP address, known as default router. Basically, it is a routing policy.
