Dict entries with numbers not tried

[wiperpaul]

I am aware that no TLDs currently have numbers in them, however when using custom entries in a dictionary file containing digits they are not attempted when the file is called to make more permutations.

for example:

abc-123 abc123

All permutations are internally filtered using the following regular expression (?=^.{4,253}$)(^((?!-)[a-zA-Z0-9-]{1,63}(?<!-)\.)+[a-zA-Z]{2,63}\.?$) which discards TLD with numbers.

What about hostnames and subdomains permuted using strings from the dictionary ?

>>> re.search('(?=^.{4,253}$)(^((?!-)[a-zA-Z0-9-]{1,63}(?<!-)\.)+[a-zA-Z]{2,63}\.?$)', '123test.nl')

<regex.Match object; span=(0, 10), match='123test.nl'>

The numeric removal is done using isalpha after splitting the dictionary file,

Removing the line fixed the issue for me and since the tld if statement is seperate from dict that part remains restricted to numerical values only.

You're correct. I just fixed this in commit 77153b3e2bfb1c015043ef344defa47f1ac2109e.
