Cheap webspace is always on a "shared host". This means you do not have a webserver, but you rent some GB on a webserver. I believe thta sub-par webdesigner is not capable of administrating an own webserver, so (e.g. for security reasons) he relies on "shared hosting". Nothing wrong with that.
1and1 then routes requests for "his" domains to a folder on one of their servers, with a "quota"-limit of the alloted GB in size.
The webserver software, e.g. "Apache", knows how to recognize domain-specific requests. It acts as a "virtual host", instead of ye olde ways where the domain name system routed http requests to a default folder on a server-identified-by-an-IP.
NEVERTHELESS these source-code hints of meta-tag-author and software used are sufficiently convincing.
Just don't waste time with all the non-running content, I'd say this is explainably irrelevant.
