robert,

what the )(*&^%$#!

oscar, you see what i mean about guyz who put the title behind names...

the rant is not aimed at the list or at oscar...

255.255.255.0...is 16 bits...hmmm... okay let do the math.

an ip address has 4 octets of 8 bits in length each
xxxxxxxx.xxxxxxxx.xxxxxxxx.xxxxxxxx

each x represents the binary 1=on or 0=off so...
from left to right the decimal values of each column are..

128/64/32/16/8/4/2/1 = octet value

if the column has a 1 in it then you add it to the next column
to the right that has 1 in until you are done scanning.
SO....
an all '1's octet = 255 in binary notation.

don't go away, robert....you need this...BAD..

so a mask of 255.255.255.0 = 11111111.11111111.11111111.00000000

hmmm...robert, are you sure of the answer you gave oscar..

are you sure this is a class 'b' with 16 bits...???

i dont think so...
