I have no idea, but it complies with the documentation. The client should request a renewal of its existing lease, which the server will acknowledge with DHCPACK if OK or a DHCPNAK if not. If the latter, then the client should do a DHCPDISCOVER. this is confirmed by the server log: ------------------------------------------------------------------ Oct 24 12:52:04 router-pi dhcpd[1068]: DHCPREQUEST for 192.168.1.254 from 0c:60:76:6c:e6:6f (tony-lt) via eth0 Oct 24 12:52:04 router-pi dhcpd[1068]: DHCPACK on 192.168.1.254 to 0c:60:76:6c:e6:6f via eth0 Oct 24 12:52:24 router-pi dhcpd[1068]: DHCPREQUEST for 192.168.1.244 from f4:81:39:82:53:c4 via eth0 Oct 24 12:52:24 router-pi dhcpd[1068]: DHCPACK on 192.168.1.244 to f4:81:39:82:53:c4 via eth0 Oct 24 12:52:32 router-pi dhcpd[1068]: DHCPREQUEST for 192.168.1.254 from 0c:60:76:6c:e6:6f via eth0 Oct 24 12:52:32 router-pi dhcpd[1068]: DHCPACK on 192.168.1.254 to 0c:60:76:6c:e6:6f (tony-lt) via eth0 Oct 24 12:52:41 router-pi dhcpd[1068]: reuse_lease: lease age 9 (secs) under 25% threshold, reply with unaltered, existing lease for 192.168.1.254 Oct 24 12:52:41 router-pi dhcpd[1068]: DHCPREQUEST for 192.168.1.254 from 0c:60:76:6c:e6:6f (tony-lt) via eth0 Oct 24 12:52:41 router-pi dhcpd[1068]: DHCPACK on 192.168.1.254 to 0c:60:76:6c:e6:6f (tony-lt) via eth0 ------------------------------------------------------------------ Enjoy your sausage rolls!
