abstract var family: Any?(source)

The record family. Must be 4, 6, or 0. For backward compatibility reasons, 'IPv4' and 'IPv6' are interpreted as 4 and 6 respectively. The value 0 indicates that either an IPv4 or IPv6 address is returned. If the value 0 is used with { all: true } (see below), both IPv4 and IPv6 addresses are returned.
