Hello Ray,
Thanx for ur reply. It was really good and informative. I had a lot of doubts
regarding sub-netting. Thanx again for clearing up my doubt.
It was not intended at really setting up a network of 32000 hosts :). Just wanted to
get sub-netting right - that's all.
Ray, It will be really nice if u could explain the term "Variable length sub-netting".
Is it the same as "Ordinary sub-netting" ?
Information from anyone will be appreciated
TIA
Sivaguru

Well ... let's see.
8192 = 13 bits ~= 8000
16384 = 14 bits ~= 16000
32768 = 15 bits ~= 32000
65536 = 16 bits = your Class B address
So there is just enough room to do what you want. One way to do it is
183.90.0.0/17 -->> ~32000 hosts
183.90.128.0/18 -->> ~16000 hosts
183.90.192.0/19 -->> ~ 8000 hosts
183.90.224.0/19 -->> ~ 8000 hosts
This works from an address-range perspective, but I assume you do realize
that most networking technologies (really, every one I know) will bog down
long before you get to 8000 hosts, never mind 320000, unless you use a lot
of switching or bridging (or more layers of routing) to isolate smaller
physical networks.
Is this what you needed to know, or were you intending something different
by your question? If so, what?
