    C-1 ip addressing scheme the viu-323 operates on an ip-based lan. Ip addresses are the addressing mechanism of the tcp/ip protocol. The ip address is composed of a 32-bit packet represented by four numbers between 0-255 separated by dots, for example: 192.36.20.198. This numbering scheme is known as...

    Appendix c c-2 the first four bits of an address determine its class. These can be represented by decimals, making it easy to identify the class of a given ip address. The following table illustrates the decimal range of the first octet of each class: class decimal range a 0 to 127 b 128 to 191 c 19...

    Appendix c c-3 a subnet mask is used to divide the suffix of the network ip address into two – the first part identifies the subnet and the second part identifies the hosts on the subnet. The subnet mask uses 1 bits to identify the network address and 0 bits to identify the host portion of the addre...

    Appendix c c-4 the solution is to use the letters a–f instead of the numbers 10–15 (in decimal), as follows:. A=10 b=11 c=12 d=13 e=14 f=15 if you add “1” to “f” (in hex) you get “10” (in hex). In decimal, “1 + f” is really “1 + 15”; thus the number “10” in hex is equal to “16” in decimal, “11” hex ...
