Dedicated IP Addresses and SNI
Last Updated -
On a VPS plan, you can purchase up to 4 dedicated IP’s at $5/IP/month. For those on Enterprise plans or higher, there is an option to purchase more but you'll need to contact support for that request.
In an effort to help preserve IPv4 addresses, the reason for the extra IPs is subject to Pagely's review and approval.
Due to the shrinking availability of IPv4 addresses, we will default to using SNI so we highly recommend you utilize SNI.
What Is SNI?
SNI (Server Name Indication) is an extension to SSL that allows multiple SSL-enabled Web sites to be served from a single IP address and port (443).
While it requires visitors to use more recent browser versions, it helps get around the problem of requiring separate IP addresses for every secure site hosted on the same Web server. This is important because IPv4 addresses are limited. Without SNI we’d run into a major problem since sites that want to run SSL are would require their own dedicated IP.
Browsers that support SNI will immediately give the name of the site they’re trying to connect with during the secure connection initialization so the server knows which certificate to send back. Visitors will not notice any difference as all of this takes place in the background
The only real downside is that older browsers and systems don’t support it, but those older browsers and systems no longer support the current security standards.
Does Having a Dedicated IP Impact My SEO Ranking?
No; Google recognizes that available IP4v addresses are limited and any current ones are just being re-shuffled. Major search engines crawl the domain name and not IP Address, which also would not offer any benefit in terms of SEO. On a fairly well-known post by Matt Cutts, that's debunked:
"They were commenting on the misconception that having multiple sites hosted on the same IP address will in some way affect the PageRanks of those sites. There is no PageRank difference whatsoever between these two cases (virtual hosting vs. a dedicated IP)."
