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.
