This is what happened to me as well. It worked for a day or so and then stopped.

I have ATT U-verse internet service and use their Arris BGW210-700 gateway

One interesting thing is that if I go to the gateway management page, and use their diagnostic tools, I'm able to ping / traceroute the address - but I can't from any devices connected to the gateway

From gateway diag page:

PING 1.1.1.1 (1.1.1.1): 56 data bytes 64 bytes from 1.1.1.1: seq=0 ttl=64 time=0.568 ms 64 bytes from 1.1.1.1: seq=1 ttl=64 time=0.156 ms 64 bytes from 1.1.1.1: seq=2 ttl=64 time=0.164 ms 64 bytes from 1.1.1.1: seq=3 ttl=64 time=0.144 ms

--- 1.1.1.1 ping statistics --- 4 packets transmitted, 4 packets received, 0% packet loss round-trip min/avg/max = 0.144/0.258/0.568 ms

traceroute to 1.1.1.1 (1.1.1.1), 30 hops max, 38 byte packets 1 1dot1dot1dot1.cloudflare-dns.com (1.1.1.1) 0.285 ms 0.177 ms 0.090 ms

The times on the pings make it look like its hitting a loopback address instead. Pings to 8.8.8.8 from the diagnostics page take about 23 ms. No way 1.1.1.1 is completing in under 1ms haha

Yes, 1.1.1.1 is in use on your Arris device, the same issue with the 5268AC since day one.
