Keybase is trying to validate an invalid TLD.

I accidentally entered *.dew not *.de but it was added and keybase tried to verify it. But because it is not a valid Domain the root-servers won't resolve it.

We could use https://data.iana.org/TLD/tlds-alpha-by-domain.txt to validate the last string after the last dot on the website and the desktop application.

Inspect the website and desktop application's domain-validation entry points, then compare their current behavior with IANA's tlds-alpha-by-domain.txt list. Verify that an invalid suffix such as .dew is rejected while a valid suffix such as .de is accepted in both applications.
