Ah. But before being forced to change a prefix, a Router could still move around as much as it wants. I think the limit is within 25m range, as imposed by the wifi 50m area (25m for two routers in opposite directions). What do you think about this practical limit? > For those scenarios it might be better to think of addressing models > in which MANET routers are configured with /128 (or /32 for IPv4) > addresses, so they don't need to change their addresses as a result > of link changes. Sorry... in the picture above the addresses are also /128. It was an abbreviation for me to show only 2001:db8:1::1/64 assigned to Host1. The full notation should have been 2001:db8:1::/64 prefix and 2001:db8:1::1/128. Would the following picture satisfy the need for /128 addresses?: ----- wifi "adhoc1" ------ wifi "adhoc2" ----- |Host1|---------------|Router|---------------|Host2| ----- LL1 P1 LL2 ------ LL3 P2 LL4 ----- G1 G4 G1, G4: IPv6 global addresses, for example 2001:db8:1::1/128 and 2001:db8:2::4/128 Manually assigned, or pre-configured with SNMP or formed according to stateless autoconf rfc4862; the prefixes are advertised by Router in RAs. P1, P2: IPv6 global prefixes, for example 2001:db8:1::/64 and 2001:db8:2::/64 Manually assigned, or pre-configured with SNMP. Or is it not what you mean? I also don't understand why you think that if /128 addresses are assigned to routers then they don't need to change them as a result of link changes. Alex
