What is the correct routing match to reach 172.16.1.5/32?
longest mask matched first
172.16.1.0/26 = Incremental value is 64, so the first subnet is 172.16.1.0 (IP address are 172.16.1.1 to 172.16.1.62) and the second subnet is 172.16.1.64 (IP address are 172.16.1.65 to 172.16.1.126). 172.16.1.0/25 = Incremental value is 128, so the first subnet is 172.16.1.0 and the second subnet is 172.16.1.128 So, the closest subnet match for the IP address 172.16.1.5/32 is /26. Hence Option A is correct
Can you explain this answer to me? I can’t understand the 255.255.255.255 subnet.
I think, it isn’t network address and subnet. But it’s a host.
