Appendix C
To represent two-digit numbers (0–15,) as a single character, the letters A–F are used, as
follows:.
A=10
B=11
C=12
D=13
E=14
F=15
If you add "1" to "F" (hex) you get "10" (hex). In decimal, "1 + F" is really "1 + 15"; thus
the number "10" in hex is equal to "16" in decimal, "11" hex is "17" decimal, etc.
The IP address is divided into four eight-bit packets. The maximum number for each packet,
in decimal, is 255, which is "FF" in hex. The subnet mask, 255.255.255.0 is represented as
FFFFFF00 (the four eight-bit packets must be represented by eight hex digits).
