Planning the network addressing scheme

Before cabling and connecting your network devices, you will need to plan your addressing scheme to make sure you have enough addresses available for each device on the network.

On the wireless router click on the GUI tab. Under the Setup tab, locate the DHCP settings for the router. These have been preconfigured so do not change them.

• i. Populate the following table with the addressing information you have located.

Router IP address	Subnet mask	Max users	First user address	Last user address	Lease time
192.168.100.1	255.255.255.0	29	???	???	0

ii.

From the router IP address and the subnet mask, calculate the network address, the broadcast address, the first usable host address and the last usable host address. Show all your working: failing to do so will limit you to half of the available marks.

Hint: you will find the logical AND will help you calculate these addresses.

iii.

Use the table below to plan the addressing for each device. To do this you will need the following information.

• The wireless router address and subnet mask are preconfigured. Hint: check these are correct.
• The web server will use the last available address of the range.
• The printer will use the second-to-last available address of the range.
• PC0 to PC2 will use the first three available addresses of the range.
• The laptop and the smartphone will be configured for DHCP later, so these addresses will come from the pool.

Device	Interface	IP address	Subnet mask	Default gateway
Wireless router	LAN	192.168.100.1	255.255.255.0
Web server	Fast Ethernet0
Printer	Fast Ethernet0
PC0	Fast Ethernet0
PC1	Fast Ethernet0
PC2	Fast Ethernet0
Laptop	Wireless0
Smartphone	Wireless0
