All 1s 128 1 2 255 In this diagram you can see the subnet mask that is 25 bits long 255 255 255 128 contains 126 members in the sub netted network Another is that the length of the network prefix equals the number of the bits with 1s in that subnet mask Knowing this you can easily count the number of IP addresses matched The following table shows the result Prefix Length INo of IP matched No of Addressable IP 132 1 131 2 130 4 2 129 8 6 128 16 14 127 32 30 126 64 62 125 128 126 124 256 254 123 512 510 122 1024 1022 21 2048 2046 20 4096 4094 119 8192 8190 118 16384 16382 117 32768 32766 17 Publication date June 2011 Revision 1 0 Signamax 065 7840C WS 24 Port 10 100 1000BaseT TX WebSmart Switch 116 65536 65534 Table 2 3 According to the scheme above a subnet mask 255 255 255 0 will partition a network with the class C It means there will have a maximum of 254 effective nodes existed in this sub netted network and is considered a physical network in an autonomous network So it owns a network IP address which may look like 168 1 2 0 With the subnet mask a bigger network can be cut into small pieces of network If we want to have more than two independent networks in a worknet a partition to the network must be performed In this case
6. IP address The address of the network device in the network is used for internetworking communication Its address structure looks is shown in the Fig 2 8 It is classful because it is split into predefined address classes or categories Each class has its own network range between the network identifier and host identifier in the 32 bits address Each IP address is comprised of two parts network identifier address and host identifier address The former indicates the network where the addressed host resides and the latter indicates the individual host in the network which the address of host refers to And the host identifier must be unique in the same LAN Here the nomenclature of the IP address we used is version 4 known as IPv4 32 bits 1 Network identifier Host identifier Fig 2 8 IP address structure With the classful addressing it divides IP address into three classes class A class B and class C The rest of IP addresses are for multicast and broadcast The bit length of the network prefix is the same as that of the subnet mask and is denoted as IP address X for example 192 168 1 0 24 Each class has its address range described below Class A Address is less than 126 255 255 255 There are a total of 126 networks can be defined because the address 0 0 0 0 is reserved for default route and 127 0 0 0 8 is reserved for the loopback function Bit 01 78 31 0 Network address

To have a port of the switch connected to a single host is referred to as micro segmentation It has the following interesting characteristics There is no need for the access contention e g Collision They have their own access domain But collision still could happen between the host and the switch port When performing the full duplex the collision vanishes The host owns a dedicated bandwidth of the port The switch port can run at different speeds such as 10 Mbps 100 Mbps or 1000 Mbps A shared hub cannot afford this 33 Publication date June 2011 Revision 1 0 Signamax 065 7840C WS 24 Port 10 100 1000BaseT TX WebSmart Switch E Vs is i 1 i E fl be Li Collision domain 2 ee Sse Le H Fi ve 1 Collision Collision Collision domain3 domain4 domain5 Fig 3 5 Collision Domain Extended Distance Limitations The diameter of a half duplex LAN segment is determined by its maximum propagation delay time For example in a 10M LAN the longest distance of a LAN segment using yellow cable is 2500 meters and 185 meters when using coaxial cable The switch with its per port per collision domain can extend the distance like a bridge does And what s more when operating in full duplex mode the distance can reach farther than half duplex because it is not limited by the maximum propagation delay time 512 bits time If fiber media is applied the distance ca
