5.3	Case C, IPv6 connectivity without provider support

...

5.3.2	Addresses and connectivity in Case C
   
   The upgraded gateway will behave as an IPv6 router; 

<MB> not the only way to do it. one host inside the internal network could
be the v6 router. Text should be fixed.</MB>

it will continue
   providing the IPv4 connectivity of non-upgraded NAT. Nodes in the
   local network will obtain:
   
   	- IPv4 natted addresses,
   	- IPv6 link local addresses,
   	- IPv6 global addresses.
   
   The clients could also obtain IPv6 site local addresses, if the
   gateway advertises a site local prefix; this raises the same issues
   already discussed in case B.
   
   There are two ways to bring immediate IPv6 connectivity on top of an
   IPv4 only infrastructure: automatic tunnels provided by the [6TO4]
   technology, or configured tunnels. 
<MB>not the only ways.</MB>

Both technologies have advantages
   and limitations, which will be studied in a companion document.
   
<MB>additional comment: I've not found text that clearly states that prefix
delegation is required.</MB>
