### Problem Description

My AdGuardHome use for home & office,I cannot set the IP whitelist who can use my AGH,but I found that,many IP will use DNS flood my AGH,such as use SERVFAIL / NXDOMAIN / packet.cf flooding something like that,1 sec flood my AGH 4-5 times.

I want to send an abuse report to the above IP's ISP,such as digitalocean and amazonaws.com etc..

but many ISP only accept txt log,do not accept attachment.

I cannot find any simple txt log in AdGuardHome

/opt/AdGuardHome/data have a querylog.json but the size is very big,and the log is very complicated

for example
