Ceridwyn,
I've just had a look at the installer (it's been a while) and if you have a set IP, then that's what you should enter when you are installing LAMS, see here in the first screen that comes up:
You can set your IP if this is fixed though (see where it says domain name), for instance:
Note that also you can set up the port in which LAMS is running on (by default is 8080). Just make sure that you have a proper firewall rule in place to allow incoming call to your computer on that particular port.
Thanks
Ernie
