Adding www infront of no-ip domain

Recently I have setup my own HTTP n FTP server.

HTTP: Apache 2
FTP: FileZilla 0.9.6a
PHP: 4.3.11 (not trying 5 yet)
OS: WinXP Pro
address from no-ip.com(free account: myserver.no-ip.info)

how do i add ‘www’ infront of my address so that i can client can access my web server by typing www.myserver.no-ip.info ?

Where to configure this? no-ip.com or my localhost Apache settings?

[EDIT:]
I also hoping to add a ‘ftp’ inront of my domain so that client accessing my ftp would type ftp.myserver.no-ip.info and more organize.[url=“http://www.myserver.no-ip.info/”]
