Each DNS server MUST:\n    - Respond within 1 second\n    - Respond accurately to both A and AAAA queries\n    - NOT respond to a NONEXISTENT query (helps to weed out bogus nameservers)\n- Compiles the worthy nameservers into `nameservers.txt`\n\nThe result is a list that's suitable to be used for any automated task, OSINT or otherwise.
