> _See [Dangerous Code|http://www.cs.utexas.edu/~shmat/shmat_ccs12.pdf] and [further commentary|https://tersesystems.com/2014/03/23/fixing-hostname-verification/] for useful background._
> When hostname verification is performed, it should use the hostname (not IP address) to match the certificate. The current code is wrongly using the address.
> In technical terms, ensure that calls to `SSLContext::createSSLEngine` supply the expected hostname, not host address.
> Please audit all SSL setup code as to whether hostname verification is enabled, and file follow-ups where necessary. For example, Akka 2.4 supports it but 2.3 doesn't ([ref|http://doc.akka.io/docs/akka/2.4.4/scala/http/client-side/https-support.html#Hostname_verification]).
