Subnetting allows you to create multiple logical networks that exist within a single Class A, B, or C network. If you do not subnet, you are only able to use one network from your Class A, B, or C network, which is unrealistic.

Each data link on a network must have a unique network ID, with every node on that link being a member of the same network. If you break a major network (Class A, B, or C) into smaller subnetworks, it allows you to create a network of interconnecting subnetworks. Each data link on this network would then have a unique network/subnetwork ID. Any device, or gateway, that connects n networks/subnetworks has n distinct IP addresses, one for each network / subnetwork that it interconnects.

In order to subnet a network, extend the natural mask with some of the bits from the host ID portion of the address in order to create a subnetwork ID.

An IP address is an address used in order to uniquely identify a device on an IP network. The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask. The 32 binary bits are broken into four octets (1 octet = 8 bits). Each octet is converted to decimal and separated by a period (dot). For this reason, an IP address is said to be expressed in dotted decimal format (for example, 172.16.81.100). The value in each octet ranges from 0 to 255 decimal, or 00000000 - 11111111 binary.

Here is how binary octets convert to decimal: The right most bit, or least significant bit, of an octet holds a value of 20. The bit just to the left of that holds a value of 2^1. This continues until the left-most bit, or most significant bit, which holds a value of 2^7.

This packet tracer lab is a continuation of a previous tracer lab.
In the previous lab, you were asked to subnet 192.168.1.0 /24 and break it up into subnets for site 1 and site 2. And you were asked to configure subnets on those sites as well as on these serial links.

In this lab, you need to subnet the network again to extend and conserve IP addresses.
An additional site has been added to the lab site 3.
What you need to do is take the subnet 192.168.1.64 /26 and subnet that to support this third site, as well as to reuse the subnet for the 3 serial connections.

Serial links only need /30 mask.
So you need to subnet the last new subnet that you get from 192.168.1.64 /26 and use /30 mask so that you can allocate that subnet to the 3 serial links.

So what you need to do once again, is break up 192.168.1.64 /26 to support as many subnets as possible with 8 hosts per subnet. It allocate the first new subnet to site 3, so in other words on the local area network over here and then take the last new subnet that you get from 192.168.1.64 and subnet that with /30 masks and then allocate those subnets to the serial links. You need to configure the routers appropriately, so this router needs to use the first IP address in the new subnet, this router the last one and the same is true for the other sites.

On the local area network at site 3, router 4 should use the last IP address in the new subnet. The switch, the second last IP address and the subnet and the hosts should be allocated IP addresses from the 1st available IP address to the last available IP address. You’re going to configure the IP addresses in the subnet manually. Previously, we used DHCP to allocate IP addresses to PCs, but in this subnet, you’re going to use static IP addresses.

Now once you’ve configured the network, verify that PCs can access Cisco.com and Facebook.com using their browsers. Cisco.com and Facebook.com are websites on the Internet. You need to verify that your PCs - PC 6, 7 & 8 can access the Internet as well as choose a PC in site 1 and site 2 and make sure that they can also access Cisco.com and Facebook.com.

So can you complete this lab?
Download the packet tracer file and see if you can complete the lab yourself, otherwise watch the next video where I completed the lab.
