[Dnsmasq-discuss] Question about behaviour of '#' symbol

[Elias LA]

Thanks Matus.

Yes, I am aware about the documentation which you quoted (and which I quoted). But how do you explain that the domain `firebaseio.com` is being blocked by set 1 and NOT by set 2?

As you mentioned, we should expect `server=/firebaseio.com/#` to lookup the domain from `8.8.8.8`. But it is not happening, and the domain is being blocked!
