[Dnsmasq-discuss] dnsmasq is offering ip from different pool

[Florent Fourcot]

Hello,

I can confirm that we suffered something maybe related on all recent 
dnsmasq versions (I never tried with something older), since several 
years (first seen in 2021, with a v2.86).

In our scenario, we had a lot of new/removed interfaces, and removing an 
interface (and associated subnet) triggered randomly the same behavior 
than yours.

However, I was never able to create a stable reproducer. At some point, 
dnsmasq started to send bad IP addresses, but I never found something to 
trigger it. It looks random.

Our current workaround : always update dnsmasq.conf to not include 
removed (or down) interfaces, and restart dnsmasq.

Best regards
