+     * (e.g., "http" or "ftp") and a scheme-specific-part.  The scheme-
+     * specific-part must include a fully qualified domain name or IP
+     * address as the host.
+     *
+     * When the subjectAltName extension contains a iPAddress, the address
+     * MUST be stored in the octet string in "network byte order," as
+     * specified in RFC 791 [RFC 791]. The least significant bit (LSB) of
+     * each octet is the LSB of the corresponding byte in the network
+     * address. For IP Version 4, as specified in RFC 791, the octet string
+     * MUST contain exactly four octets.  For IP Version 6, as specified in
+     * RFC 1883, the octet string MUST contain exactly sixteen octets [RFC
+     * 1883].
