Subnetting is the practice of dividing a network into two or more smaller networks. It increases routing efficiency, enhances the security of the network and reduces the size of the broadcast domain. Consider the following example: In the picture above we have one huge network: 10.0.0.0/24. All hosts on the network are in the same subnet, which

Mar 29, 2019 · Therefore, the full representation for our 200.1.0.64 subnet is 200.1.0.64 255.255.255.192. The subnet mask can also be represented as a prefix length which is basically the number of bits that make up the network portion (i.e. counting the binary 1s). For example, 255.255.255.192 can also be represented as /26. Subnetting Cheat Sheet The following subnet cheat sheet will not solve all of the subnetting questions on the exam. What it will do, however, is gain valuable time. Since you can't take anything into the exam, the trick is to write the following chart out on your dry-erase board before you start the exam: Class B Space is denoted in numbers of Class C's; Ripe Subnet # of Class C's /23: 255.255.254.0: 2 /22: 255.255.252.0: 4 /21: 255.255.248.0: 8 /20: 255.255.240.0: 16 Subnetting Cheat Sheet.

The subnetting cheat chart is here. Step 2. Look at the IP address and subnet mask. If the subnet mask is written out in abbreviated form (called CIDR) then just count up in blocks of eight and add the last few numbers to reach the subnet mask. e.g.
The Easy Subnetting Chart we created also produces one other pertinent number in addition to the number of subnets. You guessed it, the number of hosts per subnet. All we have to do is subtract two from the answer to the previous formula. Now the formula is 2n-2=X where n is the number of host bits borrowed to make subnets. subnetting practice - Subnetting Questions Thank you for visiting SubnettingPractice.com, the most extensive subnetting practice site on the Internet.
