Just wondering.
Could someone tell me what is the difference between http://www.hostname.com/ and http://home.hostname.com/? Or what is the significance of the omission of the www and the use of home?

www. will usually be the same as without it altogether, depending on whether the web host has enabled it (http://www.webhost.com/ and http://webhost.com).

home. is a subdomain and will usually either point to another server or to another page on the one web server, denoted by the web host configurations, for example, forum.exetel.com.au is a subdomain of the exetel.com.au domain, which is used to host these forums.

Usually, useful answers can be sought from a search engine, such as http://www.google.com.au/search?q=diffe ... subdomains.

To add a little to the above, www is not specified by the standards, but is conventionally added to server names to indicate the server type. Compare ftp and nntp for some other server types, or the unnecessary but useful, file name suffixes (.doc, .mpg) on Unix-family computers.

As the others have said, plus the sub-domain, domain names like home.hostname.com, can be used to reference a completely different sever. For example if Exetel wanted a server in Brisbane they could create the subdomain bne01.exetel.com.au and it would work on the Internet as if it were a part of the one at www.exetel.com.au. Just we wouldn't know we were switching between servers (except for the bne in my example :mrgreen: ).

It's possible that forum.exetel.com.au points to another server (probably in the same data centre) so the forum doesn't impact the main web site performance. Cool, eh?

Other (common) examples are dns1.exetel.com.au and dns2.exetel.com.au and mail.exetel.com.au and pop3.vic.exemail.com.au and so on.

Cheers,

Mike
