DHCP allocates IP addresses dynamically.  How does DHCP know 
which (fixed

a way to get this list?


Exception addresses coresponding to the printer addresses are coded into the
DHCP server.  You can obtain printer ip's by using an SNMP scanner like
SolarWinds.  Most printers have SNMP enabled by default with public
community enabled.
