From what I've seen "Server Name Indication" is the main way to achieve this at the moment.

One of the downsides is that older browsers won't support this so depending on the site it may not be a possibility for it to be used.

Edit: Just to update following @D.W.'s and @Piskvor's comments looks like there's a list of supported and unsupported browsers on the linked Wikipedia page now.

IE6 is the main browser that does not support SNI. All other popular browsers that I know of, do support SNI except:

IE8 on WinXP is quite popular, yet SNI is only supported in IE7 or above, including all versions of Internet Explorer on Windows Vista or aboveand later. Apparently it'sInternet Explorer 6, 7, and 8 on Windows XP were the main browsers that did not possible to dosupport SNI in IE on WinXP at all, but they no longer receive security updates since April 2014.
