Does anybody know of a fast and easy way to determine if 2 hosts on a network with a custom mask are part of the same subnet?

The easiest way I know is to and the addresses to determine if they are on the same subnet, don't think there is a utility in W2K to determine this.

What is the problem?

If you have a solid grasp of subnetting, you should be able to work this out by hand in less than a minute.

If not, it may take you a few minutes.

I'm with Sexy Lexy in that I do not know of any utility of the top of my head that will do this for you. If someone does know of a utility, please post because I would be interested in chekcing it out. I've always subnetted networks out by hand.

Maybe someone in the Cisco forums would know of a quicker easier way.

HTH!

WTG Spid, I never thought of that!

One of the Cisco bods might know a quick way of doing it. Like spid, I always calculate the subnets by hand then check them to make sure I haven't done something wrong.

A wasted effort you may think with so many subnet calculators out there but, it keeps the skill active and saves you having to revise subnetting for exams

Thanks for the responses. I wasn't looking for a utility. I was thinking in terms of the math approach to use if confronted with such a question on a test. I would convert the subnet addresses to binary and compare them. I was wondering what mathematical approach most people use to whiz through stuff like this. I still find subnetting tricky. You guys are talking about real world use of subnetting. I am curious, with proxy servers, Nat, firewalls, and all that kind of technology, is there really that much subnetting still going on? If so, why?

Click below for an easy to memorize handy chart you can use to solve any subnetting problem. Write it down on the provided scratch sheet before you begin your next exam, and you'll be able to solve any subnetting question you face in only a fraction of the time.

Work some practice problems with it and see why I call it the Magic Chart. I guarantee you will too! It truly is subnetting made easy!!!

I visit www.learntosubnet.com

for a little fresh up.

But most of the Time, i use Solarwinds Advanced Subnet calculator, which is awesome.

Check it out at www.solarwinds.net
i don't know, if it is still free.

Yeah, i just checked it, still free for some personal info...
