400 Hosts...

Hi all,

How do I name in my project 400 hosts ? My network address is

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......

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

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

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.

P.

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.

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.

I think we are saying the same thing.
