AT&T Broadband Users Cannot Use CloudFlare DNS Service
On April Fool Day, the Internet performance company Cloudflare announced public DNS service that can replace the domain name servers provided by existing network service providers (ISPs). With some adjustments to the device or browser, Cloudflare’s DNS service blocks browser behavior and uses data. And the point is to be faster and more reliable than the ISP’s DNS, and you can use it for free.
However, ArsTechnica cited foreign media reports, AT&T home broadband users recently encountered some trouble when using the DNS service, believe AT&T through the firmware update to prevent users from using Cloudflare’s DNS service. Then AT&T responded by saying that the problem was “unintentional conflict” and stated that it would be resolved as soon as possible.
Once upon a time @ATTcares used to promise they’d enable the future, so disappointing they now appear to be actively locking down the past and breaking Internet standards in the process. https://t.co/LPPDDtXETs

This issue was discussed in several posts in the DSL Reports user community and it is not possible to use Cloudflare’s 1.1.1.1 IP address.
AT&T’s spokesperson said: “With the recent launch of Cloudflare’s 1.1.1.1 DNS service, we have found that one out of four available IPs is conflicting with the gateway IP address, and we are currently working to resolve this issue.” DNS services are usually Internet service providers offer to resolve such as Google.com to real IP addresses that routers and switches can understand. It is an important part of the Internet, but the ISP’s DNS is usually slow, unreliable, or even intentional hijacking Internet sites for profit happen. In the event of a serious DNS failure, network access in some areas may not be available. These events have occurred many times at home and abroad.
Cloudflare and APNIC collaborate to provide DNS services through both IP 1.1.1.1 and 1.0.0.1. Also, Cloudflare, itself an internet service provider, has also used its strengths to analyze and research spam traffic to ensure that DNS resolves data accurately.
Cloudflare DNS will support DNS-over-TLS and DNS-over-HTTPS. The global average response time is 14ms, while OpenDNS is 20ms and Google’s DNS is 34ms.
This is not the first time Cloudflare has provided a free service to help the network. Several years ago they provided free SSL encryption for millions of websites. The company also provided DDoS protection to prevent websites from being flooded with malicious traffic.
