originalHostName

Reserve the original application specified hostname.

The original hostname is useful for domain-based endpoint identification (see RFC 2818 and RFC 6125). If an address was created with a raw IP address, a reverse name lookup may introduce endpoint identification security issue via DNS forging.

Oracle JSSE provider is using this original hostname, via jdk.internal.misc.JavaNetAccess, for SSL/TLS endpoint identification.

Note: May define a new public method in the future if necessary.
