Even if a *nix box doesn't run BIND, djbdns or other caching
nameservers, many run nscd ("name service cache daemon"), which caches
all libc calls to the resolver. The FreeBSD under-the-hood in the
routing engine has nscd enabled or disabled, and even if nscd is
running what is configured in nscd.conf and nssswitch.conf  ?
