I have many filters on my IP FILTER list and sometimes this blocks more than it should. It would be very usefull to know what "rule"/ipfilter filtered some ip/tracker to adjust the filter lists. It could just appear on the same message as "Destination IP filtered (48899)" by |FilterName| on trackers or "IP Filtered" by |FilterName| on Peers, in case it's easy to implement.
Many thanks!

+1, reimplementing IP search logic based on a list of subnets is tedious. I think a simpler "Find corresponding IP blocklist" feature in IP Filter or Peer list context menu would be enough too.
