getMACHints(preferIp6opt) → {Array.<Array.<string>>}

Return an array of (MAC address, name hint) tuples sorted by MAC address.

Parameters:

Name	Type	Attributes	Default	Description
`preferIp6`	boolean	<optional>	false	Whether to prefer IPv6 addresses (`true`) or IPv4 addresses (`false`) as name hint when no hostname is known for a specific MAC address.

Source: network.js, line 1967

Returns:

Returns an array of arrays containing a name hint for each found MAC address on the system. The array is sorted ascending by MAC.

Each item of the resulting array is a two element array with the MAC being the first element and the name hint being the second element. The name hint is either the hostname, an IPv4 or an IPv6 address related to the MAC address.

If no hostname but both IPv4 and IPv6 addresses are known, the preferIP6 flag specifies whether the IPv6 or the IPv4 address is used as hint.

Type:: Array.<Array.<string>>
