Practice Archetype #2C: 255.255.255.192 (/26)
Written on 15:38 by Ahmet Emir
In this additional example, we’re activity to subnet the arrangement abode 192.168.10.0 application the
subnet affectation 255.255.255.192.
192.168.10.0 = Arrangement address
255.255.255.192 = Subnet mask
Now, let’s acknowledgment the big five:
- How abounding subnets? Since 192 is 2 $.25 on (11000000), the acknowledgment would be 22 = 4 subnets.
- How abounding hosts per subnet? We accept 6 host $.25 off (11000000), so the blueprint would
be 26 – 2 = 62 hosts.
- What are the accurate subnets? 256 – 192 = 64. Remember, we alpha at aught and calculation in our
block size, so our subnets are 0, 64, 128, and 192.
- What’s the advertisement abode for anniversary subnet? The cardinal appropriate afore the amount of the next
subnet is all host $.25 angry on and equals the advertisement address. For the aught subnet, the
next subnet is 64, so the advertisement abode for the aught subnet is 63.
- What are the accurate hosts? These are the numbers amid the subnet and advertisement address.
The easiest way to acquisition the hosts is to abode out the subnet abode and the advertisement address.
This way, the accurate hosts are obvious. The afterward table shows the 0, 64, 128, and 192 subnets,
the accurate host ranges of each, and the advertisement abode of anniversary subnet:
Okay, again, afore accepting into the abutting example, you can see that we can now subnet a /26.
And what are you activity to do with this alluring information? Implement it! We’ll use Figure 3.2
to convenance a /26 arrangement implementation.
The /26 affectation provides four subnetworks, and we charge a subnet for anniversary router interface.
With this mask, in this example, we absolutely accept allowance to add addition router interface.
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
