+# 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.
