Hi,

I have some questions, and would appreciate it if some one could .

Typically when a company gets internet access for all of the nodes in
the company, do they get a subnet and network, or a whole network in
an address class (or multiple networks in an address class, so they
can supernet).

If they do get a subnet, is it possible to re-subnet? Maybe, for
example, I have a subnet with so many addresses, but I want to make
more subnets out of that subnet for security or efficiency reasons. Is
that done?

Or, do you have to just buy networks assigned by address class?

thanks.
