DHCP & Host

Host File

Create a host file mapping Blackboard to the IP address 10.10.1.81
Host files are a way of resolving domain names to IP addresses. In most OSes, the hosts file overrides and information that would be retrieved from a DNS server. You can use hosts file to you’re your network by setting up a test machine.

Because the computer no longer would have to ask the DNS server for the IP address, setting up your host file with frequently visited websites could potentially speed up your web surfing.

You can also check the hosts to see if spyware is infecting your system.

Lab - DHCP
Setup a DHCP pool on the Dlink routers.
Write a page about the lab in your blog. Include at least one screen shot of the Dlink web interface.

We set up a DLINK Router DHCP pool one day in class, but I think it was the day the port closed the bridge so I don’t remember doing this . Here are the steps to setup a the pool anyway.

1. Get into the router configuration. (unless you’ve changed the default password, you can use that)
2. You’ll want to go to, depending on the router, to the section that has DHCP settings
3. Change the starting IP address and type in the maximum # of users (on this router) on some you can tell the configuration what IP address is the last address you want to use.
4. Save the settings to the router.
5. Release and Renew your IP address and you should see the changes to you IP address take effect.
6. NOTE: Sometimes the routers require rebooting them, most of the time not.
