- At least one of ipv4 or ipv6 is required to be True, both can be True, but they cannot both be False.
- TODO: add OS fingerprinting

Hint

If you notice any issues in this documentation, you can edit this document to improve it.

Hint

Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
