## What does IP route 0.0 0.0 0.0 0.0 mean?

Explanation. IP route 0.0. 0.0 0.0. 0.0 Fa0/0 in plain English means “packets from any IP address with any subnet mask get sent to Fa0/0”. Without any other more specific routes defined, this router will send all traffic to Fa0/0.

## How high can an IP address go?

An IP address is always a set of four numbers like that. Each number can range from 0 to 255. So, the full IP addressing range goes from 0.0.0.0 to 255.255.255.255. The reason each number can only reach up to 255 is that each of the numbers is really an eight digit binary number (sometimes called an octet).

## How do you subnet?

255.248 or /29.STEP 1: Convert to Binary.STEP 2: Calculate the Subnet Address. To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask. … STEP 3: Find Host Range. … STEP 4: Calculate the Total Number of Subnets and Hosts Per Subnet.

## What is 24 subnet mask?

A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.

## What does IP address 0 mean?

All other addresses in the subnet can be assigned to hosts on that subnet. For example, IP addresses of networks with subnet masks of at least 24 bits ending in . 0 or . … means subnet ID 10.6.

## What is the subnet mask for 10.0 0.0 12?

## Why all zeros and all ones are not assigned to IP address?

255.255 could be interpreted as meaning all hosts on the network 128.9. Or, the address 0.0. … It is useful to preserve and extend the interpretation of these special addresses in subnetted networks. This means the values of all zeros and all ones in the subnet field should not be assigned to actual (physical) subnets.
