There was a question outlined in the CCNA subnetting video (Subnetting Class A) and I was wanting to confirm the correct answer. ( I understand this is neither a class A IP address nor a class A subnet. This question was just outlined in the Class A subnetting video)
The question is as follows
You've been assigned 172.31.255.128/26, how many subnets can you create?
a. 4 networks
b. 2 networks
c. 256 networks
d. >400 networks
I am just refreshing but I feel this is what is called a classless IP address and given the subnet mask, there would be 4 total available subnets we could create.
172.31.255.128 is the subnet ID. ( Incrementing by 64 )
