Thanks, that's a good point. Yes, it is certainly possible to not have a known promiscuous mode, and also of course in the case of a pcap conversion the interface is not known. We're discussing the best approach to handling this; whether to have specified 'unspecified' values, or specify that, since all config items in C-DNS are optional, values should only be present if definitely known. -- Jim Hague j...@sinodun.com Never trust a computer you can't lift.

[DNSOP] I-D Action: draft-ietf-dnsop-dns-capture-format-01.txt
A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Domain Name System Operations of the IETF. Title : C-DNS: A DNS Packet Capture Format Authors : John Dickinson Jim Hague Sara Dickinson Terry Manderson John Bond Filename: draft-ietf-dnsop-dns-capture-format-01.txt Pages : 48 Date: 2017-02-21 Abstract: This document describes a data representation for collections of DNS messages. The format is designed for efficient storage and transmission of large packet captures of DNS traffic; it attempts to minimize the size of such packet capture files but retain the full DNS message contents along with the most useful transport metadata. It is intended to assist with the development of DNS traffic monitoring applications. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-dnsop-dns-capture-format/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-ietf-dnsop-dns-capture-format-01 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-dnsop-dns-capture-format-01 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
