I've been looking this up for days, and at a complete dead end now. Everything I find basically comes down to remove the dns address, turn it off, or change the address to 1.1.1.1. None of this works.
You can see in the picture that it's turned off, and there are no saved addresses to remove. It won't even save an address if I enter one. I can't find anything else on my phone that references dns or network settings. I'm only using cell data, not connected to any wifi. Changing the setting to automatic doesn't do allow me to visit sites either. Changing a setting and power cycling the phone doesn't change anything.
I've spoken with my carrier, there are no parental blocks on my account. I'm the only person on the account. No one else has access.
When I go to a site my browser tells me the site is not secure, mentions opendns, and gives me the option to continue anyways. Doing so only routes back to the same not secure message. I can't go any further.
I have no idea how this got on my phone, but it's been on it for a couple months now. I'm sure I'm forgetting some info, but I've listed the main things. Any help would be appreciated, this is just stupid at this point.
If there's a better /c/ to ask about this in let me know. Thanks everyone!
EDIT: Lem453 got me back online with thier suggestion. Select the bottom option “private DNS hostname” and enter either one.one.one.one or DNS.google.com.
Lots of good info provided by people too in the comments. As much as this has been frustrating for me on a daily basis it's also given me new knowledge on how my phone works, so that's pretty cool.
Here is a thing about OpenDNS you might not know. It actually has parental control feature that let you filter various domains based on category. They implemented by allowing you to enter your current IP address, and then all DNS requests from that IP address will run through the selected filter: https://signup.opendns.com/homefree/
One more thing. Mobile carrier often use CGNAT, which will put a bunch of customer behind the same set of public IP address. When you're behind a CGNAT, your request will appear to come from the same IP address like other customers of the same mobile carrier in that area.
What happened to you is someone in the same CGNAT enabled parental control on OpenDNS and registered the CGNAT's public IP address as their own. This result in everyone in the same network to have their DNS requests filtered according to that user's parental control settings.
You might need to wait until you got rotated into a new public IP address, or use a VPN. The real question is why your carrier use opendns in the first place.
Only if those clients are specifically using OpenDNS as their DNS server.
Very interesting. It does have categories blocked, it's blocking r rated movies and anything violent too. That's crazy someone can screw up a whole ip address like that, if that is what happened.
Thank you for the insights
