What is the difference between a domain name and a sub domain name..?

Dear all,

I'm looking for a web hotel on which I could register several web site URLs.

I wonder what is the difference between a domain name and a sub domain name.

Thanks

Stephane

your own domain might look like this:
http://www.mySite.com

And a sub domain might look like this:
http://www.mySite.com/MyOthersite/

The physical structure is as above.

When a correct setup is done you can reach your site 'MyOthersite' as usual like this:
http://www.MyOthersite.com

Okay. With the "correct" setup, I could register domain names to sub domain names or sub directories of my web host root directory...?

Yes, your web host will make the setup for you , it's nothing you need to do from your side, exept telling them about the domains you want to activate as 'sub domains'.

By the way, do you know a good web hotel...?

Here is what I need :

I'm starting a business to offer websites for renting.

My customers will have a preinstalled website, with all their data in a database. They'll have a guestbook, a few pages and stuff...

For each customer I need :

- one sub directory on the file system (serves as the root dir of the site)
- one auto include directory directive
- one database
- one domain name
- several email ending with the domain name of the customer

And of course, as a business, I will charge for the service I am offering.


Cheers!

I only know about Swedish web hotels, and I also know that it might be hard to find a hotel that will alow second hand renting, but there might be one out there (I doubt they will give you any support for your customers thu).

Actually, a domain name is company.com.

Anything added to the left of company.com is a subdomain.

Examples:

www.company.com  - website subdomain
mail.company.com  - email server subdomain
support.company.com - support site subdomain
myhome.company.com - your personal homepage subdomain at company.com.
smtp.gateway.company.com - SMTP gateway subdomain.

Any of these could actually be referring (aliases) to locations within the www.company.com subdomain

Example: support.company.com could refer you to www.company.com/support/

Stephane -

Please post in English.  Most of us don't understand Swedish.  I know a bit of Spanish and Polish and am teaching myself Japanese, but I haven't gotten to Swedish yet... ;)

Thanx for the points.  Glad to help.
