<![CDATA[reverse resolve with DNS on Status/Dashboard]]>Hihi

On my PF-sense dashboard,Firewall logs, there are a lot of messages popping up (see image) "Reverse Resolve with DNS." Every minute.
Where from is this coming? Is this slowing down my network? How can i Fix this?

Running is an AD-environment with DHCP server.

If you need more info, let me know!

Thanks in advance.

It's ff02::fb

Google will tell you what it is (so now you know : harmless).

If needed : hunt down that device that is making these requests, shut it down / tip out the network cable :=> problem solved.
Or : do not log these inoffensive requests.

I am new to Pfsense 😭 So please tell me more 🙏
It's not one IP; there are different ones. The other thing is it's not only IPv6 also some IPv4 addresses.

Can't tell - it''s hidden behind the black ink. I guess you should know ...
I tend to say : some device on your LAN ....

You have a marvelous device called pfSense that can help you answering that question.
IMHO : no.

That's not a question. Your are the admin : you decide.
You have the IP .... so you could nail down this device : make a firewall rule that blocks that IP, the owner will show up fast (or switches over to IPv4 ^^, you will block that also, etc.)
