+# Configuration for getaddrinfo(3).
+#
+# So far only configuration for the destination address sorting is needed.
+# RFC 3484 governs the sorting.  But the RFC also says that system
+# administrators should be able to overwrite the defaults.  This can be
+# achieved here.
+#
+# All lines have an initial identifier specifying the option followed by
+# up to two values.  Information specified in this file replaces the
+# default information.  Complete absence of data of one kind causes the
+# appropriate default information to be used.  The supported commands include:
+#
+# reload  <yes|no>
+#    If set to yes, each getaddrinfo(3) call will check whether this file
+#    changed and if necessary reload.  This option should not really be
+#    used.  There are possible runtime problems.  The default is no.
+#
+# label   <mask>   <value>
+#    Add another rule to the RFC 3484 label table.  See section 2.1 in
+#    RFC 3484.  The default is:
+#
+#label  ::1/128       0
+#label  ::/0          1
+#label  2002::/16     2
+#label ::/96          3
+#label ::ffff:0:0/96  4
+#
+# precedence  <mask>   <value>
+#    Add another rule the to RFC 3484 precendence table.  See section 2.1
+#    and 10.3 in RFC 3484.  The default is:
+#
+#precendence  ::1/128       50
+#precendence  ::/0          40
+#precendence  2002::/16     30
+#precendence ::/96          20
+#precendence ::ffff:0:0/96  10
+#
+#    For sites which prefer IPv4 connections change the last line to
+#
+#precendence ::ffff:0:0/96  100
