Is it possible that https://dnsflagday.net/ will affect dnsmasq on CentOS 7?
If so what is important to do?

I have tried to compile DNSMasq  on CentOS 7 but it requires nettle-dev 3.X
which doesn't exist on CentOS 7.
I tried to compile an  RPM and I succeed but there are some blocking in the
way for upgrading 2.76 to 3.3(nettle).

Where should I put my efforts on?

Hey,

I have couple CentOS 7 hypervisors and VM's.
On the hypervisors I do not have any issue with dnsmasq as DHCP server but I
have not tried using it as a DNS.
On once machine I have the latest CentOS 7 dnsmasq version (2.7x) and for
some reason while it run's queries against a local unbound server, it seems
that it returns empty responses.
When I am querying  the same unbound service from the same machine using
tools like dig or host they answer fine.
When I am querying the local dnsmasq it returns an empty response.
How should I verify what might cause this issue?

Thanks,
Eliezer
