For http URIs: the www. prefix is just a convention: whether it's needed or not is up to the administrators who manage the parent domain name, e.g. example.com for www.example.com. If they have made an address record for example.com, and the webserver at that address accepts the name, then you can use it. Likewise for home.example.com, etc. http://www.w3.org/Provider/Style/www.html urn:ietf:rfc:2219 = http://ietf.org/rfc/rfc2219.txt http://www.useit.com/alertbox/990321_compound.html http://yost.com/misc/nix-on-www.html http://domains.dantobias.com/structure/subdomains.html For other URIs, especially non-URLs, www (if it appears at all) may be an essential part of the URI, and removing it could create a completely different URI. > Does it have to do with the browser and/or its level? No; however some Web browsers, if unable to look up an address for a domain name in an http URL, will prefix www. and try again. > Does it have to do with how domain names are registered? No, unless the registered name servers don't allow the necessary records to be created. > Any input would be most helpful. hope this helps, -- Daniel Biddle <deltab@osian.net>
