Question

Which single CIDR block correctly summarizes (aggregates/supernets) both 192.168.32.0/24 and 192.168.33.0/24 into one route, without including any additional unnecessary address space?

Q: Answer-Which single CIDR block correctly summarizes (aggregates/supernets) both 192.168.32.0/24 and 192.168...

192.168.32.024 and 192.168.33.024 differ only in the last bit of the third octet 32 00100000, 33 00100001 in binary. Removing one bit of specificity moving from 24 to 23 merges exactly these two contiguous 24 blocks into a single supernet 192.168.32.023, which spans 192.168.32.0 through 192.168.33.255 precisely the two original blocks, with no extra wasted address space unlike a 22, which would incorrectly include 192.168.32.0 through 192.168.35.255, four 24 blocks.
