AV-IO commented Oct 9, 2024

Naabu version: 2.3.1

Current Behavior:

Naabu appears to attempt IPv6 scanning even when not specified.

Expected Behavior:

IPv6 only to be scanned when specified.
While no effective scanning is taking place, I don't think scanning should be attempted at least to not pollute debug logs.

Steps To Reproduce:

  1. Run sudo naabu -host "google.com" -iv 4 -debug (ports and other options may be specified to truncate results)
  2. See debug logs including IPv6 addresses

From OSX:

# sudo naabu -host "google.com" -iv 4 -p 80,443,1234 -debug

These results are not too different from when IPv4 and IPv6 are scanned together:
