See the dnsmasq manpage for the log-queries option (note that if you
intend on processing the cache dump, you may want to configure your
system so that the log from dnsmasq is directed to a specific file
where no other process logs anything, or even avoid the system log
altogether and instead feed the dnsmasq output directly to some
process).

The dnsmasq manpage lists all TTL-related options. Watch out, dnsmasq
does not give you full control on the TTL, though.

Amicalement,
