You must input the ip-address of a webserver where you
can put your web-page files. That means you need to find
a server for hosting your web-page if your school doesn't provide
one for the project.
There are a few companies offering free web-site hosting.
To get it free you have to put up with them showing ads
on your pages.
Here are a couple free hosting providers:
Tripod
http://www.tripod.lycos.com/
Geocities
http://geocities.yahoo.com/
Angelfire
http://www.angelfire.lycos.com/
If you want cheap web-site hosting without ads on your pages
one of the cheapest I have found is GoDaddy
(I have no experience with them though):
https://www.godaddy.com/gdshop/hosting/shared.asp?se=%2B&ci=714
(apparently only $3.16/month if you sign up for 2 years)
If you want to register a domain name you can do that
in many places. godaddy.com, jumpdomain.com etc. etc.
Just look for the best price and make sure that the deal
is reasonable for the price.
