## What does 29 mean in IP address?

/29 means that 29 of the 32 bits of the address are the netmask, therefore, only 3 bits are available for differentiating between computers.

## How many subnets are in a 24?

Converting /29 gives 255.255. 255.248. This shows that the fourth octet is the interesting octet. Deducting 248 from 256 gives us 8 so the subnets are 0, 8, 16, 24, 32, 40, 48……2-3 Subnetting.Dotted Decimal ValueCIDR notation255.255.255.0/24255.255.255.128/25255.255.255.192/26255.255.255.224/2719 more rows•Dec 12, 2013

A network numbered “10.0. 0.0/8” (which is one of those reserved for private use) is a network with eight bits of network prefix, denoted by “/8” after the oblique. The “8” denotes that there are 24 bits left over in the network to contain IPv4 host addresses: 16,777,216 addresses to be exact.

## What are classless IP addresses?

Classless Addressing is an improved IP Addressing system. It makes the allocation of IP Addresses more efficient. It replaces the older classful addressing system based on classes. It is also known as Classless Inter Domain Routing (CIDR).
