WebWhat you do with the magic number is you take the value in the octet that is being subnetted. So 248 in this case, you take that away from 256. 256 minus 248 gives you 8, and now you know that the network addresses are going to go up in blocks of 8. In that example, our address was 135.15.10.138. WebMagic number=256-192=64. This tells us that what should be the gap in two consecutive subnets. In first subnet the PCs can be assigned any IP from 200.10.5.65 to 200.10.5.126. Note: – Here the interesting octet is the fourth octet as it has subnet mask (i.e. 192) rather than 255. So we see no changes in 200.10.5. lawn mower 3nylon bushing insertsWeb25 Apr 2024 · Subnetting means dividing a network in multiple small networks.

Web3 Nov 2024 · Subnetting, therefore, involves dividing the network into smaller portions called subnets. Subnetting applies to IP addresses because this is done by borrowing bits from the host portion of the IP address. In a sense, the IP address then has three components – the network part, the subnet part and, finally, the host part.
