Nothing random about it Greg. Its all hosts file based, no dhcp involved this side of the router. If the desired fqdn is not in the /etc/hosts file, which is identical on all machines (so is the /etc/resolv.conf file, which assigns the router as the nameserver and commands it to search hosts nameserver) then the dns query gets sent to the router, which is running dnsmasq. If dnsmasq doesn't have it cached, it consults the dns server given to it by my isp. In any event pings to an unknown name are usually resolved and returned in less than 90 milliseconds. Fixed ip, needed to make my web page work without paying a monthly fee for dynamic updates, is done at the router by cloning the mac of the router so that I can swap routers if I have to. My isp hand's out net ipv4 addresses according to the routers MAC. That hasn't changed in at least half a decade. There is not any ipv6 that I know of beyond the cable/phone modem. And it all Just Works, with no dhcpd drama anyplace but the router to isp modem connection. Since its a cable modem the connection is full time live barring power failure long enough to kill the cable systems backup batteries, typically nearly 24 hours. My telephone also works during this time. I have a wife in the later stages of COPD, so there is (and its a common sight locally, 5 that I've noticed in this little cul-de-sac) a 20 kw nat gas fed generator on a pad behind the garage, so I have 100% lights and AC and more importantly oxygen generation for the wife typically 5 seconds after the substation faults. Whats not to like? The router does the NAT from 192.168.xx.yy, so all machines have full access to the net, but with the exception of my web page running on a port forward, nothing here is visible from the net itself. dd-wrt, flashed into the routers, has very sharp teeth. So I've not been bothered by attacks from the network. Ever. I rather like it that way. :-) But you all claim I'm doing it bass ackward. I don't agree, and I don't fight with poisoned routes either.
