Charlie Schluting, BS in Computer Science, MBA in International Business, is a true techie at heart. His experience started in Network Engineering, then moved on to Unix Administration, Systems Architect, and eventually moved into IT operations management. This book started when Charlie worked, wrote, researched, and spoke about networking on a regular basis. To not lose touch with his networking roots, he continued developing this book, and finally finished it 4 years later :)

The author's email address is undeliverable.
subnetting has always confused me. the text on page 24 REALLY confused me.
the text says "each /26 network has 64 hosts". i followed that.
the text goes on to say "the networks run from .0 to .64, .65 to .128, .128 to .192, and .192 to .255". That's where you lost me. how can 192.168.1.128 be in BOTH the second subnet AND the third subnet?
shouldn't the addresses run as follows?
.0 to .63
.64 to .127
.128 to .191
.192 to .255
that way, each address is in one and only one subnet.
if my suggestion is wrong, then please explain.
