Since I cannot edit my above comment I post an update: After writing the above post I checked the client again, just to be sure. To my greatest surprise I found that the fec0::0:0:1::2 address was correctly assigned to it! Checked syslog on the server and found that the address was assigned 3 min

I've done the following test today on two physical machines, so no virtualization is involved. How to reproduce: What I have tried today: Installed Ubuntu 14.04 64bit (kernel 4.4.0.-38-generic) on two physical machines (no virtualization involved). Upgraded them and installed radvd and isc-dhcp-s

Same happens in Ubuntu 14.04 with kernel 4.4.0-36-generic. Also reproduced on the above 16.04 distribution. DHCPv6 server: isc-dhcp-server in IPv6 mode (isc-dhcp-server6) Wireshark captures indicate that the solicit is sent from the client, arrives to the server's network interface, then lost in
