Re: ip subnetting question [7:1607]
archselector=0 Just type the word Subnetting @ the CCO search engine & you should find (with a little digging) exactly what you are looking for. When the principles of high order bits & subnet mask #'s (i.e. /24= 255.255.255.0, etc) fall into place, the table you're referring to should be a fairly easy practice to draw out (regardless if it makes sense right away :o) Good Luck Phil PS- a good exercise book for IP addressing is: http://www.bestwebbuys.com/books/compare/isbn/0071349251 The first 3 chapter have great exercises, though it would be a total bore to read cover to cover. - Original Message - From: Sam Hebert To: Sent: Monday, April 23, 2001 12:06 PM Subject: RE: ip subnetting question [7:1607] > www.learntosubnet.com > > > Should have everything you need. > > S.H > > -Original Message- > From: Lowell Sharrah [mailto:[EMAIL PROTECTED]] > Sent: Monday, April 23, 2001 9:48 AM > To: [EMAIL PROTECTED] > Subject: ip subnetting question [7:1607] > > > Does anybody out there have a soft copy of a table that lists the subnet > mask, number of networks and number of host per subnet for class a,b, and c > networks?

I'm not exactly sure what you're looking for, but I'd suggest grabbing 3Com's Subnet calculator, which will let you select by network bits, subnet mask, subnet networks, or hosts.

RE: IP Subnetting Question
As phil has said mate, it is in the question! They have probably asked how many bits of subnetting are being used in which case the answer is perfectly correct. You are giving the answer as the full mask = natural mask + subnet mask -Original Message-From: Robert Cabeca [mailto:[EMAIL PROTECTED]]Sent: 17 October 2000 18:00To: cisco group studySubject: IP Subnetting Question I am not understanding the concept of using an IP address followed by /n.

Re: IP Subnetting Question
You must have been using that god-awful CiscoPress ACRC book. You are absolutely correct, and the book is absolutely wrong. The sad part is that these kind of mistakes are rampant in CiscoPress books, and they make you begin to doubt whether you understand the concept. It is simple. /n is the number of contiguous 1 bits in the subnet mask, period.

Re: IP Subnetting Question
Robert, You need to read up on the difference between classfull and classless networks. Take the address 100.1.0.0 The classfull mask for this network is class A which is 255.0.0.0 or /8 . There is no subnetting yet. Lets say you want to provide 8 bits of subnetting. then you have 100.1.0.0 255.255.0.0 or /16 which contains 8 bits of subnetting.
