DNS Queries for "." every second?

[tknorris]

I recently migrated to Adguard Home on linux/docker from Adguard Home in a FreeBSD Jail on FreeNAS.

In the new install I get a query for the "." domain about once every second. I never saw that on my old install. Anyone have any idea WHY that might be happening? MOST of the time it's from the docker containers own docker network, but it also occasionally comes from my router. If it's needed, is there a way to stop it from appearing in the logs? From googling, I understand this is a ROOT query, but I don't understand why I've never seen it before. Is it triggered by running the docker container in it's own network?

See #5995. Some clients seem to send them, and you can either block them completely or remove them from the logs and statistics.

Thanks, that's exactly what I needed. Issue #5990 had the info I needed to filter it out.
