Hi all,

How do I name in my project 400 hosts ? My network address is
192.168.24.0. Would it be like this:

First IP - 192.168.24.1
Last IP - 192.168.25.254
Both Mask - 255.255.252.0

Am I correct ?

minimum mask would be 255.255.254.0 (510 useable addresses)

what you have would work, but you have allowed for 1022 addresses.

Hi Stephen !

I am trying to simulate this environment but Packet Tracer 4.0 does not
allow to set this mask for this IP !

Try using a 172.16.x.x
or a 10.x.x.x

then that is a bug since the mask is valid - try setting it on a real device
such as a PC......

Re: 400 Hosts...
A 192.168 address will require at least a 24 bit mask.

unless you use "ip classless"

or just any (non cisco) box that doesnt default to rules which are more than
10 years out of date :)

Re: 400 Hosts...
Is this not some form of "simulator?"
Perhaps the the 'sim' wants the operator to stay within another set of
rules.....

could be.

so - either it is a "cisco" simulator (or why use this group) - in which
case ip classless is fairly key to understanding how a cisco handles IP once
you get past the basics.

or it isnt - in which case there should be a set of rules somewhere to
check....

FWIW i think it more likely it is broken rather than operating a different
rule set.

I think we are saying the same thing.

192.168.24.0 is a class c address and you can only get 254 host from it.

You cannot say it is a "class c" without the associated mask. It may look like
one, it my be generally accepted that addresses in that range would normally be
a /24, but it is an unsafe assumption.

These days make sure you always write the mask with a network address.

thats true as far as it goes - but "class" based addressing hasnt been best
practice for a long time - ever since internet address space allocations of
"bunch of class C" (or set of /24) numbers became common.

shame that most intro IP texts still seem to introduce addressing using
classes before they get to the simpler more flexible classless stuff.
