Practice Example #3C: 255.255.255.224 (/27)
Written on 15:39 by Ahmet Emir
This time, we’ll subnet the arrangement abode 192.168.10.0 and subnet affectation 255.255.255.224.
192.168.10.0 = Arrangement address
255.255.255.224 = Subnet mask
- How abounding subnets? 224 is 11100000, so our blueprint would be 23 = 8.
- How abounding hosts? 25 – 2 = 30.
- What are the accurate subnets? 256 – 224 = 32. We aloof alpha at aught and calculation to the subnet
mask amount in blocks (increments) of 32: 0, 32, 64, 96, 128, 160, 192, and 224.
The subnets (do this first) 0 64 128 192
Our aboriginal host (perform host acclamation last) 1 65 129 193
Our aftermost host 62 126 190 254
The advertisement abode (do this second) 63 127 191 255
122 Chapter 3 Subnetting, VLSMs, and Troubleshooting TCP/IP
- What’s the advertisement abode for anniversary subnet (always the cardinal appropriate afore the
next subnet)?
- What are the accurate hosts (the numbers amid the subnet cardinal and the broadcast
address)?
