Hi 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. Rune
