Hi Alper, Greg. I'm not flaming, and not try to generate any heat :-) Greg Daley wrote: That's right. This gives the option to use LCoA with a CN if MN wants to. So, location privacy is an optional feature for MN to use, unlike with the NATs. Actually, I think that MN can decide about its use

Alex, So, an idea is that the location privacy might be a problem, and that Mobile IPv6 might offer a site-local-free solution for that problem, and that HMIPv6 needs site locals in order to provide a solution to that problem. This is not a correct conclusion. As I have explained earlier,

Alper, I tried to draw a logic conclusion from this: -I assumed LCoA and RCoA have same last 64 bits -I was countered that that is not absolutely necessary, and that rfc 3041 could be used. -I replied: yes, could, but it is not. -I was pointed that site-locals might be used too. -so I concluded.

Hi Greg, Greg Daley wrote: There is no problem with the RCoA and LCoA differing only in prefix if the LCoA and RCoA are based on RFC3041 addresses. A-ha, that sounds like a tangible goal. I mean there is a big if in your phrasing. I still need to understand how this would work in practice

Hi Alper, Just a quick note. Alper Yegin wrote: [much text cut] To me, there are some common points, but there are also huge differences. I'm thinking about in NAT there is a specific set of types of addresses (the not publicly-routable) that can be reused by any site at will. However, with
