Name-based hosting is when hosting sites share a single IP address, with site traffic directed by the server to the appropriate hosting account by examining 'host headers'. IP-based hosting accounts come with a unique IP address that is not shared with anyone else. At any time, for an additional $1.00 USD per month, you can convert a name-based account to an IP based account.
Some of the features that require IP based hosting are:
- Purchasing your own SSL certificate and using your own domain name for SSL access (secure socket layer).
- Anonymous FTP (file sharing) for your visitors is not possible under name-based hosting.
- Running scripts or software that requires a unique IP.
