That is not 100% correct. By default, dhclient will send an initial DHCPREQUST to 0.0.0.0 (meaning "this network"). The request is picked up from the DHCP server broadcasting on 255.255.255.255. -- Glen Barber _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
