Changing IP address

[Grub]

In Windows I could set a domain to be a different IP address by adding a line to a file called hosts (in system32). Is it possible to achieve the same thing in Linux?

[Jordan]

Yes, there is a 'hosts' file in Linux as well. It generally resides in /etc/ named 'hosts' = /etc/hosts

Edit it the same way as you would in Windows.

You could also use iptables for this but would be a bit complicated for such a simple task.
