*.compute-1.amazonaws.com return none on base_domain

[Kuzuto]

Have anyone same problem ?

In utils.py on line 100:

    psl = publicsuffixlist.PublicSuffixList()
    return psl.privatesuffix(domain)

When psl.privatesuffix is getting ec2-100-24-188-149.compute-1.amazonaws.com, it returns 'None'.

I made a test in /parsedmarc/venv/lib/python3.7/site-packages/publicsuffixlist/test.py

    def test_amazonaws(self):
        self.assertEqual(self.psl.privatesuffix("ec2-100-24-188-149.compute-1.amazonaws.com"), "amazonaws.com")

This return None 'amazonaws.com' != None Expected :None Actual :'amazonaws.com'

If only using compute-1.amazonaws.com , it works:

    def test_amazonaws(self):
        self.assertEqual(self.psl.privatesuffix("compute-1.amazonaws.com"), "amazonaws.com")

PASSED [100%] Process finished with exit code 0

Should the base_domain = get_base_domain(reverse_dns) in line 416 in utils.py not have returned amazonaws.com ?

Same problem with psl.privatesuffix("nabieyilan.beget.app") This also return None. Should this not return "beget.app" ? In tests.py I made this test update , and is failing:

    def testPSLDownload(self):
        subdomain = "foo.example.com"
        result = parsedmarc.utils.get_base_domain(subdomain)
        assert result == "example.com"

        # Test newer PSL entries
        subdomain = "e3191.c.akamaiedge.net"
        result = parsedmarc.utils.get_base_domain(subdomain)
        assert result == "c.akamaiedge.net"

        # Test nabieyilan.beget.app
        subdomain = "nabieyilan.beget.app"
        result = parsedmarc.utils.get_base_domain(subdomain)
        assert result == "beget.app"
