Maybe the rule can be concretely: 1. if you have something else/better use that, otherwise 2. if you have a domain name, include SNI, and finally 3. if you don't have a domain name (including IP literals), do whatever. The HTTP scheme permits a broader range of "host" identifiers than we usually contemplate, so the 3rd option has to catch more than just IP literals. TLS was always necessarily lax because different applications have different constraints, but the idea was to ensure that for cases where you have the ability to use SNI that you used it. -- You are receiving this because you are subscribed to this thread.
