Hello,

It seems any string composed of numbers separated by dots is now accepted by the domain validator.

>>> validators.domain("123.123")
True

>>> validators.domain("123.123.123")
True

>>> validators.domain("123.123.123.123")
True

It didn't use to be the case (I know because it now causes some errors in my unit tests in the "naval" library)
I think it was good that these strings weren't accepted as domains. I don't think these are valid domains.
