MSI Posted October 13, 2008 Share Posted October 13, 2008 I was watching our installer set up some new equipemnt and the DNS was different for different devices. Is DNS required for each controller/navigator ? In System Manager Under DNS Servers, Using DHCP=No, What should the DNS server address be set to ? Our router has the DNS set to the Comcast supplied ip address's. Link to comment Share on other sites More sharing options...
K&J Posted October 13, 2008 Share Posted October 13, 2008 I set a couple of different DNS's usually one for crapcast or sbc and another say 4.2.2.2 etc.. Link to comment Share on other sites More sharing options...
Matt Posted October 14, 2008 Share Posted October 14, 2008 Yes every control device talks to the internet someway, so it does need a dns for every ip device. If you go to start, run, and type cmd (hit enter). Then type ipconfig /all you can find your dns there.I also use one from an open dns to be safe: 208.67.222.222 or 208.67.220.220 provided from http://www.opendns.com/Best pratice would be to set the first one to the gateway of the router, the second one to the isp, and the third one to the opendns provided above.

TurboKuake Posted October 14, 2008 Share Posted October 14, 2008 You should be using the router's IP for your DNS server. Link to comment Share on other sites More sharing options...
MSI Posted October 14, 2008 Author Share Posted October 14, 2008 Do you mean the DNS IP that is used in the Router setup to communicate with the ISP or the internal ip of the router (192.168.x.x) ? Link to comment Share on other sites More sharing options...
TurboKuake Posted October 14, 2008 Share Posted October 14, 2008 The IP of the router itself, Usually 192.168.x.x Link to comment Share on other sites More sharing options...
Matt Posted October 14, 2008 Share Posted October 14, 2008 The ip address you login into the router would be used for the dns. Link to comment Share on other sites More sharing options...

Comcast Dns seems to go out often enough that is why I add an additional open Dns. Link to comment Share on other sites More sharing options...
ATOH Posted October 21, 2008 Share Posted October 21, 2008 If you use the router IP as the DNS you're relying on the router to pass the correct information on to the controller. This in turn has caused update issues. Your better off using your ISP's DNS server IPs at a minimum and then, like others have said, a verified open DNS server. You can find your ISP DNS information in your router's status screen (or whatever it may be called in your brand's software) and typically if you have a PC set up to use DHCP you can find the DNS information in the command prompt using the command ipconfig /all.4.2.2.2 is also a great tool for troubleshooting, as are any other open DNS servers. This way you can test when you don't seem to have internet access if your ISP's DNS server is working correctly. Link to comment Share on other sites More sharing options...
