                          disable explicit source port randomisation and rely
                          on the kernel to provide random source ports
+  --enable-linux-ip-local-port-range
+                          Define this to enable use of
+                          /proc/sys/net/ipv4/ip_local_port_range as a default
+                          outgoing port range. This is only for the libunbound
+                          on Linux and does not affect unbound resolving
+                          daemon itself. This may severely limit the number of
+                          available outgoing ports and thus decrease
+                          randomness. Define this only when the target system

+apply.
+\fI<action>\fR has generally the same semantics as that for
+\fIaccess-control-tag-action\fR, but there are some exceptions.
+.IP
+Actions for \fIresponse-ip\fR are different from those for
+\fIlocal-zone\fR in that in case of the former there is no point of
+such conditions as "the query matches it but there is no local data".
+Because of this difference, the semantics of \fIresponse-ip\fR actions
+are modified or simplified as follows: The \fIstatic, refuse,
+transparent, typetransparent,\fR and \fInodefault\fR actions are
+invalid for \fIresponse-ip\fR.
+Using any of these will cause the configuration to be rejected as
+faulty. The \fIdeny\fR action is non-conditional, i.e. it always
+results in dropping the corresponding query.
+The resolution result before applying the deny action is still cached

+.B response-ip-data: \fI<IP-netblock> <"resource record string">
+This requires use of the "respip" module.

+record string" is similar to that of \fIaccess-control-tag-action\fR,
+but it must be of either AAAA, A or CNAME types.
+If the IP-netblock is an IPv6/IPV4 prefix, the record
+must be AAAA/A respectively, unless it is a CNAME (which can be used
+for both versions of IP netblocks).  If it is CNAME there must not be
+more than one \fIresponse-ip-data\fR for the same IP-netblock.
+Also, CNAME and other types of records must not coexist for the same
+IP-netblock, following the normal rules for CNAME records.
+The textual domain name for the CNAME does not have to be explicitly
+terminated with a dot ("."); the root name is assumed to be the origin

+.B response-ip-tag: \fI<IP-netblock> <"list of tags">
+This requires use of the "respip" module.
+.IP
+Assign tags to response IP-netblocks.  If the IP address in an AAAA or
+A RR in the answer section of a response matches the specified

+Then, if an \fIaccess-control-tag\fR is defined for the client and it
+includes one of the tags for the response IP, the corresponding
+\fIaccess-control-tag-action\fR will apply.
+Tag matching rule is the same as that for \fIaccess-control-tag\fR and

+Unlike \fIlocal-zone-tag\fR, \fIresponse-ip-tag\fR can be defined for
+an IP-netblock even if no \fIresponse-ip\fR is defined for that
+netblock.
+If multiple \fIresponse-ip-tag\fR options are specified for the same

+Actions specified in an
+\fIaccess-control-tag-action\fR that has a matching tag with
+\fIresponse-ip-tag\fR can be those that are "invalid" for
+\fIresponse-ip\fR listed above, since \fIaccess-control-tag-action\fRs
+can be shared with local zones.
+For these actions, if they behave differently depending on whether
+local data exists or not in case of local zones, the behavior for
+\fIresponse-ip-data\fR will generally result in NOERROR/NODATA instead
+of NXDOMAIN, since the \fIresponse-ip\fR data are inherently type
+specific, and non-existence of data does not indicate anything about
+the existence or non-existence of the qname itself.
+For example, if the matching tag action is \fIstatic\fR but there is

 .B primary: \fI<IP address or host name>
 Where to download a copy of the zone from, with AXFR and IXFR.  Multiple
 primaries can be specified.  They are all tried if one fails.
+To use a nondefault port for DNS communication append '@' with the port number.
+You can append a '#' and a name, then AXFR over TLS can be used and the tls authentication certificates will be checked with that name.  If you combine
+the '@' and '#', the '@' comes first.
+If you point it at another Unbound instance, it would not work because
+that does not support AXFR/IXFR for the zone, but if you used \fBurl:\fR to download
+the zonefile as a text file from a webserver that would work.
+If you specify the hostname, you cannot use the domain from the zonefile,
+because it may not have that when retrieving that data, instead use a plain
+IP address to avoid a circular dependency on retrieving that IP address.
