Having problems connecting to 1.1.1.1


#1

Hi there!

I’ve been using your awesome DNS service for some time, but recently, I’m unable to connect to DNS 1.1.1.1, 1.0.0.1 works fine thought, I would like to know what I could try to fix it, I’ve used your connection information tool, you can find some of the information it produced on this link: Information

I hope you can help me recover connection to the DNS service, thank you in advance for your time!

Whatever you’re connecting to on 1.1.1.1 looks to belong to Google. What device (computer/tablet/etc) are you using? And what network hardware (router, wireless access point)?

Hi @sdayman, thanks for your reply :).

I use a Linksys WRT 3200ACM and a modem supplied by my ISP, which is Axtel in Mexico, the modem from my ISP doesn’t allows me to change the DNS server, so I have to make the change using the configuration interface on my Linksys Router, as I said before, the DNS service used to work without a problem for a while, probably a month since I switched to it and got it working perfectly, but a few days ago, the router sent some alerts that it couldn’t connect to the Internet and when troubleshooting, I found that I couldn’t connect to 1.1.1.1 anymore, but 1.0.0.1 still works well, so I changed the DNS servers of my router to use 1.0.0.1 and 8.8.8.8, so that might explain why google appears there.

Can you do a Traceroute to 1.1.1.1 and post the results here?

Hi, sure!

This is the result of the traceroute in windows:

tracert 1.1.1.1

That should be enough. It looks like your ISP isn’t letting it through. @mvavrusa might have more information on this.


#7

Thanks, @Firebrand we’ll try to reach out to the ISP. It seems like you use mixed resolvers, so you get mixed result between 1.0.0.1 and 8.8.8.8 (the test site generates multiple queries). But it confirms you can’t reach 1.1.1.1 or any of the IPv6 addresses.

@mvavrusa, Thank you for your reply, I’ve already talked with my ISP provider as well, they raised a report of the issue as well and they commented something like a blacklist of IP addresses, not sure if you could do something about that.

Thanks for your time, I really appreciate your help in fixing the issue.
