RFC 9110 section 4.3.5: "A reference identity of IP-ID contains the decoded
bytes of the IP address. An IP version 4 address is 4 octets, and an IP
version 6 address is 16 octets. [...] A reference identity of type IP-ID
matches if the address is identical to an iPAddress value of the
subjectAltName extension of the certificate."
