If you know you might be having nameserver troubles, one thing you could do
is reconfigure the critical systems like postfix, that use only one address
to connect outwards (sendmail equivalent of smarthost) would be to set it to
the direct IP address.

But yes, I think all programs that do use the name service should use it in
the order specified in /etc/hosts
