[comp.protocols.tcp-ip] Subnetting Class B Internet Number

mmccorm@d.cs.okstate.edu (McCormick Martin) (06/20/91)

We have a class B Internet number.      While our Ethernet
 isn't subnetted now, it may be some day.  What is the most
 efficient, (allowing the most IP numbers),  method for
 subnetting and what does each local host have to have in its
 configuration to work properly in such an environment.
     I have heard conflicting information from many
knowledgeable people and would like to hear pros and cons
from those who have actually done this.  I'll post a summary
of answers.
Thanks.

You should read RFC 1219 about this.  It doesn't discuss
all the pros and cons of every possible method, but does
give one method that is the best known (I think) but requires
variable-mask routing protocols like OSPF.
