mksub 
Generate tens of thousands of subdomain combinations in a matter of seconds
Read a wordlist file and generate subdomain combinations for a given domain or list of domains. Input from the wordlist file is lowercased and only unique words are processed. Additionally, wordlist can be filtered using regex.
When you use mksub's `-l` parameter, it will generate all subdomain combinations up to the specified level, including all lower levels, using words from the wordlist. For instance, with `-l 2`, it will generate `len(permutation_list)^2 + len(permutation_list)` results, which is:
- 30 combinations for a 5-word wordlist.
- 10100 combinations for a 100-word wordlist.
- 250500 combinations for a 500-word wordlist.
