Google DNS can't find IP addresses

Wisewiz · Feb 8, 2023

I have no idea where to start trying to solve this problem: I repeatedly get these notices that my server can't find the addresses of places whose addresses it knows perfectly well. I'm using the Google DNS at present: 8.8.8.8 and 8.8.4.4, and that server should be able to find ANYthing immediately.

I'm in the country, and on satellite, but that shouldn't be relevant.

Any suggestions you make will be carefully considered and followed up.

Try checking the status on Google Public DNS

If you can't reach that, check the DNS at Troubleshooting | Public DNS | Google Developers

Traceroute and connection status all OK.

Thanks for responding to my request for help. Much appreciated.

Configure OpenDNS servers on Windows for faster and safer web browsing. OpenDNS servers: 208.67.222.222 and 208.67.220.220

Trying that now. Restarted after reset. Now It'll take a while to see whether I get those "Can't find IP" messages again. They aren't consistently there. (They mainly pop up when I really want to GO somewhere on the Net.)

Thanks for the suggestion. I'll report.

Set the OpenDNS to run, and restarted. A few minutes later, I got this:

try to flush your DNS Cache...

Open an admin command prompt and type the following:

Batch:

ipconfig /release
ipconfig /renew
ipconfig /flushdns

Another thing to try is set the DNS servers to automatic as provided by your ISP. Do that in Windows and on your router or satellite thingy.

@Archigos and @kelper:

Will try both of your suggestions as soon as I can. Thanks to both of you.

Okay, so far I've switched from Google to Open DNS on both my desktop and my router, and I've flushed the DNS cache.

Since I finished adjusting those settings, I've had no new "can't be reached" pop-ups. Time will tell. So far, so good.

If the router is set to OpenDNS you could leave the computers set to automatic. (DHCP)

If you travel with a laptop, manually setting your DNS can prevent you connecting to wifi in hotels etc.

@kelper
Router settings and computer settings all set now. Still testing.

The same problems continue to plague me. Please read my post #1 above, and see whether you have any new ideas. Any help gratefullly accepted.

Please try setting DNS to automatic on computer and router.

Wisewiz · Feb 9, 2023

I have IP assignment set to automatic. I don’t think you can set DNS to automatic. You have to specify a DNS or you’ll just get your ISP’s default.

kelper · Feb 9, 2023

That's correct. Why don't you want to test the ISP's DNS servers?

Try this for analysing lots of DNS servers to find the quickest/most reliable.

Used default for years, and was unhappy with its resolution speed. Google and OpenDNS are much faster and more reliable.

kelper · Feb 9, 2023

until now! I run Steve Gibson's utility from time to time and the ISP's DNS servers come top. I'm just suggesting you try them again, at least they worked even if OpenDNS and Google were subjectively quicker.
