    Appendix C 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 0 to 127...

  • Page 115: Figure 22 - Class C Subnet Mask

    Appendix C 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 address.
  • Page 116 Appendix C 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”...
