What you really need to understand is what you'll do with this knowledge! you'll discover in determine 4-1 that either subnets were assigned to a router interface, which creates our broadcast domain names and assigns our subnets. Use the command convey ip path to see the routing desk on a router (covered intimately all through this book). determine 4-1: imposing a category C /25 logical community i do know this isn’t precisely everyone’s favourite hobby, yet it’s quite vital, so simply hold in there; we’re going to discuss subnetting—period. you must be aware of that the major to figuring out subnetting is to appreciate the very cause you want to do it. And I’m going to illustrate this through facing the method of creating a actual network—and let’s upload a router. (We now have an internetwork, as i actually wish you recognize! ) o.k., simply because we further that router, to ensure that the hosts on our internetwork to speak, they need to now have a logical community addressing scheme. lets use IPv6, yet IPv4 continues to be the preferred, and it additionally simply occurs to be what we’re learning for the time being, so that’s what we’re going with. Okay—now have a look again to determine 4-1. There are actual networks, so we’re going to enforce a logical addressing scheme that enables for 2 logical networks. As continually, it’s a truly stable concept to appear forward and examine most probably progress scenarios—both brief and long-term, yet for this instance, a /25 will do the trick. perform instance #2C: 255. 255. 255. 192 (/26) during this moment instance, we’re going to subnet the community deal with 192. 168. 10. zero utilizing the subnet masks 255. 255. 255. 192. 192. 168. 10. zero = community deal with 255. 255. 255. 192 = Subnet masks Now, let’s solution the massive 5: what percentage subnets? because 192 is two bits on (11000000), the reply will be 22 = four subnets. what percentage hosts consistent with subnet? we've got 6 host bits off (11000000), so the equation will be 26 – 2 = sixty two hosts. What are the legitimate subnets? 256 – 192 = sixty four. take note, we begin at 0 and count number in our block dimension, so our subnets are zero, sixty four, 128, and 192. What’s the published handle for every subnet? The quantity correct sooner than the price of the subsequent subnet is all host bits became on and equals the printed handle. For the 0 subnet, the subsequent subnet is sixty four, so the published deal with for the 0 subnet is sixty three. What are the legitimate hosts? those are the numbers among the subnet and broadcast tackle. one of the best ways to discover the hosts is to put in writing out the subnet deal with and the published tackle. this fashion, the legitimate hosts are visible. the next desk indicates the zero, sixty four, 128, and 192 subnets, the legitimate host levels of every, and the published tackle of every subnet: ok, back, ahead of stepping into the following instance, one can find that we will be able to now subnet a /26. And what are you going to do with this interesting details? enforce it! We’ll use determine 4-2 to perform a /26 community implementation. The /26 masks presents 4 subnetworks, and we want a subnet for every router interface. With this masks, during this instance, we really have room so as to add one other router interface.
