The .SE Registry has created a solution that stores queries and answers.


PacketQ (replaces DNS2DB)

PacketQ is a tool for analyzing PCAP-data, if can work with any packets 
but is designed primarily for DNS and ICMP-traffic. PacketQ reads, 
filters and groups the packets read from the PCAP-files using standard 
SQL-queries. The tool is built in C for performance and portability. The 
distribution also includes a simple interactive GUI for analyzing the 
collected data.
