It's neater and safer to keep static and dynamic addresses in separate ranges, but often not strictly necessary. DHCP servers are supposed to ping an address before assuming it's unused. That normally means you can get away with manually allocating IP addresses inside a DHCP range. Unless some well-meaning person has blocked all ICMP, or disabled the DHCP server's ping address check. -Warren Block * Rapid City, South Dakota USA
