Yeah. A typo. I’m afraid my tale of woe is unlikely help future readers, **except** to know that you can use `tcpdump` to watch port 53. That was the saving grace.

The actual typo was somehow I copy-pasted `dns-nameservers` in twice, so I had

```plaintext
uto enp1s0
iface enp1s0 inet static
  address 38.242.7.195/28
  gateway 38.242.7.193
  dns-nameservers dns-nameservers 1.0.0.1 1.1.1.1

```

rather than

```plaintext
  dns-nameservers 1.0.0.1 1.1.1.1

```

And DNS worked all the time except, inside of docker. (Docker used only the first entry rather than using the next one if the first failed?)
