One of the first things I do on a new windows installation is usually jump over to the hosts file and add an entry for "router" pointing to "192.168.0.1" because it saves time typing the address. I've got bored of doing this though - and if you use OpenDNS shortcuts to do it for you, you can simplify this procress.

If you're on OpenDNS, head over to the dashboard, and click the "Shortcuts" tab. You can then specify a shortcut to point to an internal IP address - making the process of accessing that device quicker and easier.
