No, IP addresses are not DNS names. And IP address SANs are octet strings, 4 bytes for IPv4 and 16 bytes for IPv6. There is a mapping of IPv4 and IPv6 addresses to reversed dotted quads for reverse resolution. Examples: 1.0.0.127.in-addr.arpa. IN PTR ? 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa. IN PTR ? But in all other ways IP addresses are definitely NOT domain names. -- Viktor. _______________________________________________ Uta mailing list Uta@ietf.org https://www.ietf.org/mailman/listinfo/uta
