Hi!
Looking at the attached pcap file you can see a DNS packet with 5 Answer
records.
The 4th Answer record is of type KEY.
In Wireshark you can see there's a "Key id" field for this Answer record.
This field is not defined in RFC 4034 (http://www.ietf.org/rfc/rfc4034.txt).
Wireshark also doesn't show where is the value for this field comes from.
I have no idea where did this field came from and I believe it should be
removed.
Thanks,
Boaz.
