What does 29 mean in IP address?

/29 represents 29 of the 32 bits of the address are the netmask hence only 3 bits are available to distinguish the computers. However, you always lose 2 addresses from the block for broadcast and loopback, so the result is: 2^(32-29) – 2 = 2^3 – 2 = 8 – 2 = 6. We have only 5 usable addresses on /29 allocations.
