Hi Russell, Is this a problem? Our systems running with the old ISC DHCP server report /128 on Ubuntu boxes for addresses handed out by DHCPv6 even though link local addresses appear as /64. In a sense all host addresses are /128 entries. The important thing is that the routing table includes a route for the /64 block containing the address. As long as that is there your system should work properly. That should be learnt from the RA rather than DHCP.

I have configured a DHCP6 range and a pool but the client always has a ::/128 address. As I have a mixture of staticly assigned and dhcp6 clients in the same ::/64 subnet, I have specified my ::/64 subnet in the { "id": 2012, "pools": [ { "pool": "NNNN:PPPP:QQQQ:T:ffff::/80" } ], "subnet": "NNNN:PPPP:QQQQ:T::/64", "interface": "eth0", "option-data" : [ { "name": "domain-search", "csv-format": true, "data": "euclid.plato" }, { "name": "dns-servers", "data": "NNNN:PPPP:QQQQ:T:8213:1132:6645:2222" }, { "name": "sntp-servers", "data": "NNNN:PPPP:QQQQ:T:8213:1132:6645:2222" } ] } How I can I assign a ::/64 address which is selected from only a smaller portion of the ::/64 subnet so that the client is assigned a ::/64 address.
