[NTLUG:Discuss] ...a little binary IP help, please...

[Fred James]

I am trying to understand the binary representation of an IP address,
and the process of ANDing with the (sub)netmask.
The book states that the decimal address 192.168.0.20 would be 11000000
01101000 00000000 00010100 in binary, and then labels those bytes as
192.68.0.20
I thought the place values were: 256 128 64 32 16 8 4 2 1, in which case
x.x.0.20 is OK, but the 192.168.x.x, or 192.68.x.x seems wrong.
Any help would be appreciated.
