[Dnsmasq-discuss] Suggestion: use arp rather than ping to check for
addresses in use in DHCP

While checking out dnsmasq, I noticed that it uses an ICMP-ping to
determine if an IP-address is already in use, before allocating it to
a new DHCP-lease.
I could not help wonder, if it wouldn't be even better to send an
arp-request (like the arping-program). After all, some computers have
personal firewalls that block pings, but I don't think it is possible
to block arp.
