+IPv4 and IPv6 usage
+-------------------
+
+Following settings affect client part of the resolver,
+i.e. communication between the resolver itself and other DNS servers.
+
+IPv4 and IPv6 protocols are used by default. For performance reasons it is
+recommended to explicitly disable protocols which are not available
+on your system, though the impact of IPv6 outage is lowered since release 5.3.0.
+
+.. envvar:: net.ipv4 = true|false
+
+   :return: boolean (default: true)
+
+   Enable/disable using IPv4 for contacting upstream nameservers.
+
+.. envvar:: net.ipv6 = true|false
+
+   :return: boolean (default: true)
+
+   Enable/disable using IPv6 for contacting upstream nameservers.
+
+.. function:: net.outgoing_v4([string address])
+
+   Get/set the IPv4 address used to perform queries.
+   The default is ``nil``, which lets the OS choose any address.
+
+.. function:: net.outgoing_v6([string address])
+
+   Get/set the IPv6 address used to perform queries.
+   The default is ``nil``, which lets the OS choose any address.
