I have been learning subnetting using material from my
MCSE books. This book states that when determining the
valid subnets you should not use the all 1's or all 0's.

However, I have been looking at Microsoft's Technet site
and they stated that this is now a dated idea, so long as
your routers use CIDR

I am planning to take my exam in the next week and I'm now
in the delima of do I use the all 1's and 0's network id
when calculating the subnetted network ids

For those interested, here is the link to MS Technet where
I found the information

http://www.microsoft.com/technet/treeview/default.asp?
url=/technet/prodtechnol/windows2000serv/reskit/tcpip/part1
/tcpch01.asp

Do a search for RFC 1812, located just above Step 3:
Enumerating IP Addresses for Each Subnet

Anyone out there have any advice regarding which way I
should go?

Thanks

Paul

For the amount of subnetting questions your likely to actually get on the
test, I wouldn't worry about it. Bare in mind if its pertinent to the answer
something will have likely been said in the statement/question.

>You're right , Microsoft uses the CIDR Notation now ,

Example : if you have an ID Address 192.168.117.110/24
It means your subnet mask is 255.255.255.0

Because number 24 means in binary

11111111 11111111 11111111 00000000 so you must have (24)
of (1) in your subnet mask

Count the subnet mask

But be careful about some exceptions

Also , you must learn about how to supernet

I passed 216 yesterday...did not get any subnetting questions

Thanks to everyone for your feedback on this subject

I was going to take the exam on Saturday, however, this
Saturday is all booked out, so I have brought the exam
forward a day to Friday

Fingers Crossed!
