I'm using libcurl to send HTTP requests to a specific IP address, but with a

Yes it should indeed. We've discussed that before on this list, we just
haven't gotten any working code for it yet so thanks a lot for your work!
libcurl currently sets the TLS Server Name Indication value to the URL's
host name. This makes it impossible to use Server Name Indication in the
described use cases. The attached patch solves this problem by setting the
Server Name Indication value to that of the custom Host header, if any.
Any feedback about this patch would be greatly appreciated.
Peter Sylvester pointed out[1] previously about the hostname in SNI:
"HostName" contains the fully qualified DNS hostname of the server
Literal IPv4 and IPv6 addresses are not permitted in "HostName".
The existing Curl_inet_pton() checks in the code makes sure of that, but not
after this patch.
The Curl_inet_pton() checks against conn->host.name in the code needs to be
modified accordingly in your patch to check the 'hostname' variable instead.
Don't you agree?
