The standard for naming FTP is usually ftp.yourcompany.com. If your domain name is registered, your virtual anonymous FTP services are in this standard format.

Anonymous and Non-Anonymous FTP
Your Virtual Server supports anonymous FTP (which allows users to access files via FTP without entering a username and a password) and non-anonymous FTP (which requires a username and password). When anonymous FTP is configured, users simply enter "anonymous" as their username and their e-mail address as their password. In other words, with anonymous FTP, you don't have to set up specific FTP accounts in order for users to access files on your Virtual Server via FTP.

Your Anonymous FTP Directory
Anonymous FTP is the safest way to grant users access to the virtual FTP service, because users are restricted to your home FTP directory. When you restrict user access and permissions, you limit potential harm that users can cause.

Your FTP directory is your home directory, and, by default, it contains only the pub sub-directory. The pub directory contains the archive files available to anonymous FTP customers. You should place files the customers need to access in the pub directory. You can create other directories as needed.
