I almost forget to mention that there is a possible issue with URL https://IPv4_IP_address and https://[IPv6_IP_address]. SSL certification, at least for the domain name, will not cover https:// protocol and IP address combinations. Are insecure URL https://IPv4_IP_address and https://[IPv6_IP_address considered possible man-in-the-middle attack vulnerabilities?
