open dns only works on a pc

February 12, 2019 18:11

I have already configured openDns on my router, but it only works where I set it, it does not work on devices and other PCs (ipv6 is disabled and ipv4 is automatic)

I need more information. Copy & paste the complete plain text output of the following diagnostic commands to here, from a PC where it does not work.
```
nslookup -type=txt debug.opendns.com.
nslookup whoami.akamai.net.
netsh interface ipv4 show config
```
Also, post a screen shot of the router page where you have configured OpenDNS.

This is not plain text, but screen shot images. :(

Regardless, unlike you said, IPv6 is *not* disabled , but you're using 2806:10b8:ffff:2::e as DNSv6 server address which is your ISP's DNS service.

Instead of disabling IPv6, you better configure IPv6 with the DNS server addresses ::ffff:d043:dedc and ::ffff:d043:dcde

Sorry I had not noticed, I've already solved thank you very much, one more question in mobile phones knows what could be the problem that does not connect?

Are you talking about OpenDNS on mobile phones? Can you be more specific about "does not connect"? Where does it not connect to?

Also, OpenDNS is a service for networks you own, not for your devices in other networks.

Yes, I mean that mobile devices are in the same network as PCs but these are not affected by restrictions

They are not? Visit http://welcome.opendns.com/ on these devices to ensure that they are using OpenDNS at all.

If they are not using OpenDNS, then check their network settings to ensure that they obtain them automatically via DHCP from the router, and that they do not have alternative DNS server addresses configured. There are also apps which establish a dummy VPN connection in order to use custom DNS services. This would circumvent OpenDNS as well.

Yes, cell phones get them automatically by DHCP and I'm not using any kind of VPN, so I do not understand what the fault could be

Well, maybe there is no fault. What are the evidences for faults? Are they not using OpenDNS?

Also, what OSes are these mobile devices? Android, iOS, Windows, or what? And what browsers are you using on them?

They are an Android system, they use Chrome as a browser and when I check if they are using opendns I get an x, but they are connected to the same network with dhcp, the pc works well

"when I check if they are using opendns I get an x"

Ah yes, they are not using OpenDNS at all! Disable the "Data Saver" option in Chrome. This is "any kind of VPN" or proxy which circumvents any other configured DNS service like OpenDNS.
In addition, you may want to add compress.googlezip.net and check.googlezip.net to your "always block" list.

Btw, as almost, the knowledge base is your friend: https://support.opendns.com/hc/en-us/articles/227989047
You must just read it. You did not need to raise it here again.

Yes, this is exactly what I said above a while ago.

if they have them, the chrome settings do not work, sometimes out of nowhere you want to enter the sites and if you block them, and other days it just does not work.
