Subnetting
Subnetting's definition
Subnetting is a methodic to increase network ID of a network ID that has. subnetting's case example: One firm gets address network's IP brazes c 192.168.0.0. With that network's IP therefore will be gotten as much 254 (28 - 2) address's internet protocol address that we can assemble on connected computer to network. One that as problem is how bring off network by totals computer more than 254 that. Obviously may not if you shall place computer as much that deep one location. If you just utilize 30 deep computers one offices, therefore available 224 address's IP that won't be used. To mensiasati totals disused address IP that by way of divide network's IP becomes many network that the so called smaller subnet.
Remember formula to look for there are many subnet is 2 n – 2
N = total bit those are veiled
N = total bit those are veiled
And formula to look for host's amount per subnet is 2 m – 2
M = total bits that was veiled
M = total bits that was veiled
Sample case with i. working out:
address's IP 130.200.0.0 by subnet mask 255.255.224.0 one is identified as class B.
Subnet mask: 11111111. 11111111. 11100000. 00000000
3 bits from octet 3rd was utilized, tingal 5 bits that was veiled therefore a lot of subnet's group that can be used is multiple 2 5 = 32 (256 – 224 = 32)
32 64 96 128 160 192 224
So IP group that can utilize dalah;
subnet loopback 130. 200.0. 0 130.200.31.254
130. 200. 32. 1 130.200.63.254
130. 200. 64. 1 130.200.95.254
130. 200. 96. 1 130.200.127.254
130. 200. 128. 1 130.200.159.254
130. 200. 160. 1 130.200.191.254
130. 200. 192. 1 130.200.223.254
