+=head3 Network permissions
+
+Network rule permissions are implied when a rule does not explicitly
+state an access list. By default if a rule does not have an access
+list all permissions that are compatible with the specified set of
+local and peer conditionals are implied.
+
+The create, bind, listen, shutdown, getattr, setattr, getopt, and
+setopt permissions are local socket permissions. They are only applied
+to the local socket and can't be specified in rules that have a peer
+conditional. The accept permission applies to the combination of a
+local and peer socket. The connect, send, and receive permissions are
+peer socket permissions.
+
+=head3 Mediation of inet/inet6 family
+
+AppArmor supports fine grained mediation of the inet and inet6
+families by using the ip and port conditionals. The ip conditional
+accepts both IPv4 and IPv6 using the regular representation of four
+octets separated by '.' for IPv4 and eight groups of four hexadecimal
+numbers separated by ':' for IPv6. Contiguous leading zeros can be
+replaced by '::' once. On a connected socket, the sender and receiver
+don't need to be specified in the recvfrom and sendto system calls. In
+that case, and with unbounded sockets, the IP address is none, or
+unknown. Unknown or Unbound IP addresses are represented in policy by the
+'none' keyword. When the ip conditional is omitted, then all IP
+addresses will be allowed: IPv4, IPv6 and none. If INADDR_ANY or
+in6addr_any is used, then the ip conditional can be omitted or they
+can be represented by:
+
+ network ip=::,		#allow in6addr_any
+ network ip=0.0.0.0;	#allow INADDR_ANY
+
+The network rules support the specification of local and remote IP
+addresses and ports.
+
+ network ip=127.0.0.1 port=8080,
+ network peer=(ip=10.139.15.23 port=8081),
+ network ip=fd74:1820:b03a:b361::cf32 peer=(ip=fd74:1820:b03a:b361::a0f9),
