isc-dhcp-server 4.1.ESV-R4-0ubuntu5.11 (amd64 binary) in ubuntu precise

 This is the server from the Internet Software Consortium's implementation of
 DHCP. For more information, visit http://www.isc.org.
 .
 Dynamic Host Configuration Protocol (DHCP) is a protocol like BOOTP
 (actually dhcpd includes much of the functionality of bootpd). It
 gives client machines "leases" for IP addresses and can
 automatically set their network configuration.
