Implementing a Class C /25 analytic network
Written on 15:37 by Ahmet Emir
I apperceive this isn’t absolutely everyone’s admired pastime, but it’s absolutely important, so aloof adhere in
there; we’re activity to allocution about subnetting—period. You charge to apperceive that the key to understanding
subnetting is to accept the actual acumen you charge to do it. And I’m activity to demonstrate
this by activity through the action of architecture a concrete network—and let’s add a router. (We now
have an internetwork, as I absolutely achievement you already know!) All right, because we added that router,
in adjustment for the hosts on our internetwork to communicate, they charge now accept a analytic network
addressing scheme. We could use IPX or IPv6, but IPv4 is still the best popular, and it additionally just
happens to be what we’re belief at the moment, so that’s what we’re activity with. Okay—now
take a attending aback to Figure 3.1. There are two concrete networks, so we’re activity to apparatus a logical
addressing arrangement that allows for two analytic networks. As always, it’s a absolutely acceptable abstraction to
look advanced and accede acceptable advance scenarios—both abbreviate and continued term, but for this example,
a /25 will do the trick.
