Corrections to Chapter 2 of Java Network Programming, Basic Network Concepts

p. 15: In Figure 2-1 "The Physical Layer" should probably be "The Host-to-Network Layer"

p. 22: In the third paragraph "105,000" should be "65,000"

p. 23: Figure 2-3 places the zeroes in the wrong positions. The correct figure looks like this:

Class Byte 0 Byte 1 Byte 2 Byte 3 Address Range
A 0 Network Host 1.0.0.0 to 127.255.255.255
B 10 Network Host 128.0.0.0 to 191.255.255.255
C 110 Network Host 192.0.0.0 to 223.255.255.255
D 1110 Multicast Address 224.0.0.0 to 239.255.255.255
E 11110 Reserved for future expansion 240.0.0.0 to 247.255.255.255
