- | !!Important ->!! Carving the ULA/48 into ULA/64's that will result in a 1:1 mapping to a GUA/60 is important to understand. In the example above we used ''IPv6/nn'' entries of ''<ula>:1::1/64'' and ''<ula>:2::1/64'' (where ''<ula>'' is shorthand for ''fd06:d115:91f1''). For a ULA/60 the largest possible sequence is ''<ula>:0::1/64'' to ''<ula>:f::1/64'', which are 16 possibilities, but be careful the first ''<ula>:0::1/64'' can't be used since that will conflict with the first "Assign GUA Prefix", since they are indexed 0, 1, etc. . If we had selected a second "Assign GUA Prefix" (index 1) we would have to start the ''IPv6/nn'' entries with ''<ula>:2::1/64'' or higher, best to start a little higher. | + | !!Important ->!!
