I must admist, I've only read the parts you pointed out, but so far
I'm very much impressed with how they managed to totally confuse the
reader with incorrect statements and wrong examples. The section on
IPv6 is probably best removed or mostly

No HTML version yet, and it's not in the same depth as the 3com

For example, on page 3:

232 what?
It should read:
2^32(to the 32rd power)
Could be an issue with special characters in

23 = CIDR notation, .. i.e. 32 bits - 23 bits for the network = 8 for the
subnet

You should work on your mathskills a bit, Lee ;)

Looks like the exponentiation operator got eaten up somewhere. 2 to the 32nd
power (2^32) is
4,294,967,296. 2^3 == 8.

Sounds like the superscript notation for exponentiation was lost
