Steps to reproduce:

I'm running the official test suite from Public Suffix website:

Actual results:

All rules pass on my implementation but these 3:

# Listed, but non-Internet, TLD.
checkPublicSuffix('example.local', NULL);
checkPublicSuffix('b.example.local', NULL);
checkPublicSuffix('a.b.example.local', NULL);

The issue is according to the effective TLD names local shows up as a valid TLD.  See

Expected results:

Looking at the comment in the test file
'# Listed, but non-Internet, TLD'
It seems to indicate that there is a way to know if its a non-Internet TLD?  By looking at the effective TLD list how do we know which ones are 'non-internet'?

There is no programmatic way to know.

We plan to sort the list into (terminology for the two groups is subject to change):

- ICANN registrar-controlled Public Suffixes (e.g.
- Privately-controlled Public Suffixes (e.g.

However, .local is an odd case. I'm not sure what we'll do with that...

Since there is no programmatic way to know, I would recommend taking .local out of the test file for now, until you build a new rule for intranet based TLDs.  

I like the idea of distinguishing out official ICANN registrar suffixes and pseudo-private suffixes.
