[Dnsmasq-discuss] Local install recommendation?

[Paul Chambers]

My config contains both my ISP's servers and those of OpenDNS. Works
like a charm.

I'd previously used ISC's bind & dhcpd (with a rather convoluted,
hard-to-maintain configuration) to do what dnsmasq does in a
straightforward manner. It seems faster doing it, too.

My machine's static, so I don't need to do this, but dnsmasq can use the
dns server info that your dhcp client (dhcpcd or pump?) writes into
resolv.conf in addition to servers like OpenDNS that you configure
separately in dnsmasq.conf.

It's best to reconfigure your dhcp client to leave /etc/resolv.conf
alone and write its version of resolv.conf elsewhere, then point dnsmasq
to use that. Otherwise local processes doing DNS lookup will use the ISP
DNS servers directly, bypassing dnsmasq and its cache.

Simon has done a really nice job with dnsmasq, you should be able to
make it do exactly what you want with a minimum of fuss.
