VB6 - DNS Monitor

$

DNS Monitor Version 2.5 is a DNS query capture and display utility. It utilizes Windows Packet Filter Kit 3.2.3 from NT Kernel Resources, which is available for download free of charge for personal use. This version of the Filter Kit supports IPv6, and loads on all current versions of Windows (including 64 bit). Upgrading Version 1 to work with this latest version of "NDISRD.sys" required a fair amount of change, so I have posted this latest version separately. This version has a few more options, including the ability to filter out all but IPv4 or IPv6 DNS queries. Like version 1, it also has the abilty to examine all packets and display both IPv4 and IPv6 queries. This mode is of course quite a bit more resource hungry.

DNS Monitor also uses MSCOMCTL.OCX, which the user must have available. This version does not include the service component, as the demand for that component was very low and involved a substantial amount of rework.

DNS Monitor supports IPv6, but as usual it has undergone very limited testing for this particular protocol because of the lack of a native IPv6 network other than local. If someone has access to such a Wide Area Network, I would appreciate feedback.
