+#    This default differs from the tables given in RFC 3484 by handling
+#    (now obsolete) site-local IPv6 addresses and Unique Local Addresses.
+#    The reason for this difference is that these addresses are never
+#    NATed while IPv4 site-local addresses most probably are.  Given
+#    the precedence of IPv6 over IPv4 (see below) on machines having only
+#    site-local IPv4 and IPv6 addresses a lookup for a global address would
+#    see the IPv6 be preferred.  The result is a long delay because the
+#    site-local IPv6 addresses cannot be used while the IPv4 address is
+#    (at least for the foreseeable future) NATed.  We also treat Teredo
+#    tunnels special.
