arp address resolution

[Sergey Naumov]

Hello.

Some programs (ex. arp) are trying to resolve addresses (even if they
are specified in xxx.xxx.xxx.xxx form). In the case of arp it is
possible to use "-n" option to prevent it, but is there a way to
disable address resolution globally? Removal of /etc/hosts works for
me, but is it possible to allow resolver look only into /etc/hosts and
make it return error if there is not an appropriate entry? Now it
tries to resolve even IP addresses and exits by timeout 3 times per IP
address.

Thanks in advance,
Sergey Naumov.
