Shared IP refers to the use of one IP by many domain names. Due to the scarcity of the IP Address space, the use of Shared IP is recommended.
The use of Shared IP is made possible by the HTTP 1.1 standard, which is in widespread use by all modern browsers. The HTTP 1.1 protocol sends the requested domain name in the request header, enabling the web server to identify the correct web site it should return.
Myths About Shared IP
- Search engines won't crawl / index your site if it is on a shared IP. This myth is completely wrong now. All search engines will add your site to their index regardless of whether it is using shared or dedicated IP address.
- Shared IP is bad, Dedicated IP is good. Once again, without any real reason, this is simply wrong.
Dedicated IP refers to the use of one unique IP Address per domain. Dedicated IP is required for any of the following circumstances:
- Your site requires the use of an SSL Certificate such as www.yourdomain.com
- Your site requires the Virtual / Anonymous FTP feature
