Because of the way web servers and SSL work, previously a dedicated IP address was required for running an SSL certificate on a domain.

But with a new technique (SNI, abbreviation for Server Name Indication) this is no longer a requirement. So which browsers do and do not support SNI?

    +1 for the effort but readers would do well to also read the SNI Support page over on Wikipedia which is more complete. Commented Oct 6, 2014 at 18:42

    Additional note: Although not a browser per-say, Bingbot and Yahoobot agents/browsers technically don't support SNI nor FS. They still index https mode though.
