I can offer two reasons why it might be so. The first is that there's a
bug in dnsmasq, which is not unheard-of, but this is old code and a bug
has not been observed before. The second is that you're running dnsmasq
configured to always send broadcasts, using the --dhcp-broadcast option.

Check all the dnsmasq configuration files, that's the sort of thing that
gets slipped in because is solves someone's problem one time, and "it
can't do any harm".


Cheers,

Simon.
