A note to Piranha:
Be careful of blast/flame and who you piss off here. Many people on this
list are high level/ranking industry-types. And people are only trying to
help one-another, so lets not get into a pissing contest - as we all "pee"
the same color.
A note to Oscar and anyone else interested:
For the record, based upon Piranha's somewhat messy example of subnetting,
the subnet of 255.255.255.0 is a 24-bit subnet mask (aka 255.255.255.0/24).
The first 24 of the 32 bits of the IP mask being ON, with the last 8 (the
last octet - 8 per octet) being OFF (aka 0).
With Classless InterDomain Routing (CIDR) prevailing, you shouldn't find
mention of Class "X" designations anymore. As the word "classless"
implies - there are no longer any classes. When you see CIDR IP addressing,
there should be a "/" following the IP address, along with a number
representing the number of bits to be used in the subnet mask.
example:
192.168.1.0/24
The above example would designate the 192.168.1 network, with a subnet mask
of 255.255.255.0 (24 bit subnet mask). In this example of CIDR, you don't
need to be concerned about giving a "title" to your network type
(A,B,C,etc). You only need to know that a 24-bit subnet mask allocates your
network nodes addresses 192.168.1.1 through 192.168.1.254.
I highly recommend that you take a course or pick up a book on TCP/IP.
Preferably, get yourself a Cisco book - since you are using Cisco products.
