    en.wikipedia.org/wiki/Server_Name_Indication

    This enables the server to select the correct virtual domain early and present the browser with the certificate containing the correct name. Therefore, with clients and servers that implement SNI, a server with a single IP address can serve a group of domain names for which it is impractical to get a common certificate.

That is, *.example. does not match all names in the example. zone; it fails to match the names below *.example.. To cover names under *.example., another wildcard domain name is needed—*.*.example.—which covers all but its own subdomains.

While not very thorough, this validation is strong enough to often be used for whitelisting purposes, since spammers and phishers ...
