Can't connect in Windows 10 -- DNS problem?

I’ve searched and read everywhere and everything, to the best of my ability; I’m a novice, forgive me if I’m asking a redundant question.

Something problem prevents communication to internet addresses, but pinging works fine. Any suggestions?

[Windows 10 Pro, updated today, 16 G,
Docker 18.09.0, build 4d60db4. – default configuration
Firewall off.]

Here’s what I get trying to test a connection. The forum wouldn’t let me post with google address with a real dot so I spelled it out.

Same response if I enhance the command with a --dns parameter using either or the DNS server reported by ipconfig, regardless of what network I’m on.

PS C:\WINDOWS\system32> docker run busybox nslookup

Here are ping results

PS C:\WINDOWS\system32> docker run busybox ping -c 1
