The advantages are:

  1. Security - packets must be routed between subnets
  2. Performance - packets will stay within their own subnet for the most part
  3. Troubleshooting - it is easier to find a problem in a smaller network than a large one.

What is a subnet mass?

An area of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices whose IP Addresses have the same prefix. Dividing a network into subnets is useful for both security and performance reasons. IP networks are divided using a subnet mask.


How many subnets are required to support three networks?

What is a subnet in computer networks?

A portion of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix. For example, all devices with IP addresses that start with 100.100.100. would be part of the same subnet. Dividing a network into subnets is useful for both security and performance reasons. IP networks are divided using a subnet mask.


Can a router be used to connect to different parts of the same networks?

Yes, especially if the networks employ subnets.


What is the differce between subnet and wide area network?

Subnets are designed for local area networks (LANS) that are used in an organization or building. Wide area networks cover larger areas and don't use subnets.


What information is required prior to dividing a netowrk into subnets?

What is ment by subnet?

It means that a larger network has been divided into smaller networks, called "subnets". Each subnet has its own range of IP addresses, that should not overlap with the other subnets.It means that a larger network has been divided into smaller networks, called "subnets".

Discontiguous Networks.


Why should wireless and wired networks be on separate subnets?

because you have to have a host Ip address to send certain destination packages


Several reasons to divide a network into subnets?

Networks are divided into smaller subnets to reduce the size of broadcast domains, but mainly for administrative purposes - so you can control who has access to what, for example.Networks are divided into smaller subnets to reduce the size of broadcast domains, but mainly for administrative purposes - so you can control who has access to what, for example.Networks are divided into smaller subnets to reduce the size of broadcast domains, but mainly for administrative purposes - so you can control who has access to what, for example.Networks are divided into smaller subnets to reduce the size of broadcast domains, but mainly for administrative purposes - so you can control who has access to what, for example.


What does it mean to borrow 4 bits for subnets?

When you borrow bits for a subnet you are intruding into the client portion of an IP address. As a result, you will lose clients in your network because the "borrowed" portion becomes the extended network prefix. This allows you to separate your bigger network into smaller, logical networks (subnets). The number of bits borrowed will indicate the total number of smaller subnets that you can support in your network. In each case, regardless of class of address, borrowing 4 bits gives a total of 14 subnets (in the classical sense) and 16 subnets (in Cisco).


How many bits do you need to borrow in a class C subnet masks to accommodate 18 networks?

Borrow 5 bits (for 30 subnets total).
