Just a quick one today, pointed out by @crayons.
I use the built in Sites feature on my Mac for internal development purposes. Something I’ve noticed is that the I.P. address I need to access keeps changing. It was really starting to get annoying.
When I mentioned it to @crayons, he pointed out that I can change the options on my network settings from ‘Using DHCP‘ to ‘Using DHCP with manual address‘.
Now before you do that, copy down the I.P. address and then all you’ve got to do is just paste it into the relevant text box.
Simples!

The “Using DHCP with manual address” will only work with an Airport, or other router which supports DHCPINFORM – In effect6, you mac is asking the router’s DHCP server to assign it a specific IP address. If your router ignores this request, then your network will break altogether.
Ultimately, the DHCP server has authority over which IPs are assigned where, so anybody not using an Airport will need to login to their router control panel to set a fixed IP for their machine.
Most routers will allow you to assign fixed IP addresses to specific devices on your network. They do this based on the devices MAC address.

Correction Airport DOES NOT support this:

Don’t know which routers do.

Doesn’t localhost just work as well? Or 127.0.0.1?

Yeah, but if you want to send the url to someone else to view, say at work over the network for example.
You need a specific I.P. address not just your localhost.
Otherwise all it’ll show them is what’s on their localhost.
