[issue32958] socket module calls with long host names can fail with idna codec error

Just to be clear, I don't know if the socket needs to support 64 character long host name sections, so here's an example url that is at the root of my problem that I'm pretty sure it should support:

>>> import socket
>>> h = "username:long_api_key0123456789012345678901234567890123456789 at www.example.com"
>>> socket.gethostbyname(h)
Traceback (most recent call last):
  File "/Users/ablack/miniconda3/lib/python3.6/encodings/idna.py", line 165, in encode
    raise UnicodeError("label empty or too long")
UnicodeError: label empty or too long

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeError: encoding with 'idna' codec failed (UnicodeError: label empty or too long)
