5. Find the number of addresses in a block of classless addresses if one of the addresses is 101.10.2.8/29.
Total addresses=
Usable addresses=

explain the process

Solution

Since we have network address of 29 bits, we have only 3 bits left for host address.
Hence, total addresses are 2^3=8.

However, since 2 addresses are reserved, we are only left with 6 usable addresses.
