Question

12. If you have a network with 300 computers explain how you would setup an IP address scheme to meet the needs of the network

(draw this if necessary)

1. If you get a computer that has the wrong IP address and is assigned via DHCP how can you get a new address? Answer for command line and gui. What does it mean when you get a 169.x.x.x address?

Answer 1

our demand is 300 computers and IP class C gives us 256 computer per subnet so what we can do we merge 2 subnet 256+256=512 so we get 512 hosts in 1 subnet and our demand is 300 computers so lets do that

Subnet 1 : 192.168.0.0 to 192.168.0.255
Subnet 2 : 192.168.1.1 to 192.168.1.255

so we merge above two subnets

Merged subnet 192.168.0.0  
Subnet mask : 255.255.254.0
Usable Host : 510  
Range : 192.168.0.1 to 192.168.1.254  
Broadcast : 192.168.1.255

Step 2

Type ipconfig /release at the prompt window, press Enter, it will release the current IP configuration.

Step 3

Type ipconfig /renew at the prompt window, press Enter, wait for a while, the DHCP server will assign a new IP address for your computer.

If you get 169.x.x.x IP that means that computer could not find the DHCP server or route to the server so kindly ping to the gateway router and server to confirm that it is properly configured. This address results from a built in feature of windows called automatic private IP address(APIPA). When your computer is unable to find a DHCP server the APIPA service will assign itself a 169. x.x.x IP address. According to Microsoft, the APIPA service checks for a DHCP server every five minutes.
