A whole bunch of lines like this in log. What does it mean?

Why would an ad be attacking my system?
The message says "possible DNS-rebind attack" because it resolves to a non-standard address. Often it's a loopback address used for media streaming apps (Amazon does this). In this case it resolves to 255.255.255.255 which is kinda pointless.

Are you going to any Polish websites?

Is there any way to know which device in the network is triggering this event? I've been getting a ton to domain ignore.me for awhile now, and suspect it's the firestick but how to know for sure? Tried searching it out on google a couple times and hit dead ends. I can't morally unplug the firestick in questionfor any amount of time to see if the message goes away, because it's pretty much a 24 hour lifeline to elderly parent living with us.

Run this command:
Code:
killall dnsmasq; dnsmasq --log-async --log-queries
and then look in the syslog for something like this:
Code:
Jul 12 02:09:32 dnsmasq[22472]: query[A] ignore.me from 192.168.1.49
Then do:
Code:
service restart_dnsmasq
 
You have a client on your lan that is checking for WAN connectivity, so there is a task that is going to look for a DNS entry...

the dns-rebind warning suggests that it's resolving to your subnet...
