<DIV><FONT face=Calibri>HI Géza,</FONT></DIV>
<DIV><FONT face=Calibri></FONT> </DIV>
<DIV><FONT face=Calibri>Given IPv4's imminent depletion at the RIR level,
dual-stacking without tunneling or translation will be a short term solution
too. Pure dual-stacking, up to the consumer's premise, assumes you are laying
out dual-stack (with both IPv4 and IPv6 enabled) nodes from core up to
the CPE, and the customer is getting both IPv6 and IPv4 public addresses, and
the latter is very scarce. </FONT></DIV>
<DIV><FONT face=Calibri></FONT> </DIV>
<DIV><FONT face=Calibri>So for v4 and v6 to coexist for the next 10 years or so
we need tunneling, or some form of IPv6-only at the customers terminal with
translation to IPv4 if needed.</FONT></DIV>
<DIV><FONT face=Calibri></FONT> </DIV>
<DIV><FONT face=Calibri>Hence my /32 endorsement for all IPv6 access
methods.</FONT></DIV>
<DIV><FONT face=Calibri></FONT> </DIV>

<DIV><BR></DIV>Hello Ahmed,<BR><BR>Many thanks for forwarding the comparison
table.<BR><BR>Temporary solutions are usefull in the transition phase. However,
I would prefere emphasize even in the address allocation mechanism if a solution
is temporary and should go away in long term. Therefore I fully agree with
János, the smallest address space the best in case of 6RD and other
non-real-dual-stack method.<BR><BR>Géza<BR><BR>

implement 6RD and TSP for both sides of the tunnel.</FONT></DIV>

<DIV><BR></DIV>Hi<BR><BR>We would like to weigh in here.<BR>We feel that it
should be RIPEs policy to allocate ONE /32 to any LIR <BR>who requests it for
6rd.<BR><BR>6rd is the only way for us to reach all our residential customers.
<BR>Especially those in Municipal Networks that are very slow to invest in
<BR>their networks and often do not have the competence and time to
<BR>impelment IPv6.<BR><BR>Also, Cisco has not yet implemented even a small
part of the protective <BR>mechanisms we rely on in IPv4 to secure our
residential networks. Many <BR>of these features are required to meet the
demands contracted with the <BR>customers. We cannot use native IPv6 until
Cisco implements these <BR>features and we have tested and rolled them out on
hundreds of switches.<BR><BR>6rd bypasses all these issues. IF we can get a
/32 for that purpuse.<BR><BR>-- <BR><BR>Med Vänliga Hälsningar - Best
