network design

Discontiguous masks are something that is going to be somewhat historic within the network design toolbox. It is basically a methodology of looking at particular bits of a network/host definition. The big thing to recall is that as a packet crosses a network device it does so within a packet. The packet is nothing more than a stream of bits. Within the packet header there are bits that define the source network address and the destination network address.

So I thought I would put out a few thoughts on this front. What is Segmnentation in Networking #Segmentation is a methodology to create separatet zones of sorts of various traffic types. Various places you may want to do this is within a campus environment to separate students from faculty, or engineering from finance.
