ATT Hijacks all DNS and no way to disable it

ATT equipment blocks all DNS queries on port 53 so there is no way to use your own DNS server config on a local machine or local router. All requests on port 53 get hijacked and routed to ATT DNS servers. Disabling the setting on the ATT website for the hidden “DNS error assistance” did not do anything. The supplied modem firmware does not have any customizable DNS server settings so impossible to change there. This is an huge invasion of privacy and security by ATT just so they can build profiles on all their users for advertising.  Will be leaving ATT if this is not fixed ASAP.

FYI, Those are MAC addresses allocated to Ubiquiti, Roku, and SonicWall, respectively.

Did you reply to the right thread?

Yes, but I was replying to a post further down the thread - someone asked what three devices, listed by MAC address were and I just looked up the MAC addresses and posted the manufacturer names.

I've looked through this thread after both of your comments and have yet to see 3 MAC addresses listed.  The only MAC address shown in the entire thread is from the adapter information on a windows PC.  Mind quoting what you are replying to?
