What does 29 mean in IP address?

To explain what it actually is: /29 means that 29 of the 32 bits of the address are the netmask, therefore, only 3 bits are available for differentiating between computers. However, you always lose 2 addresses from the block for broadcast and loopback, so your result is: 2**(32-29) – 2 = 2**3 – 2 = 8 – 2 = 6.

What is IP loopback address?

A loopback address is a special IP address, 127.0. 0.1, reserved by InterNIC for use in testing network cards.
