Looks like ULAs to me:

$ ifconfig
enp4s0    Link encap:Ethernet  HWaddr 1c:6f:65:4a:85:15
           inet addr:192.168.1.221  Bcast:192.168.1.255  Mask:255.255.255.0
           inet6 addr: fd14:4bf7:d5bf:0:1e6f:65ff:fe4a:8515/64 Scope:Global
           inet6 addr: fd14:4bf7:d5bf:0:4c4c:afde:fb87:7981/64 Scope:Global
           inet6 addr: fdf9:a66:2cd8:1::221/64 Scope:Global
           inet6 addr: fd14:4bf7:d5bf:0:b52e:f578:ce6b:8ceb/64 Scope:Global
           inet6 addr: fe80::1e6f:65ff:fe4a:8515/64 Scope:Link
           inet6 addr: fd14:4bf7:d5bf:0:d3bd:3a12:6018:90cb/64 Scope:Global


fd14... = magic to me, fdf9... = the ULA I made up and configured. Yesterday,
the fd14:4bf7:d5bf:0/64 prefix was fdec:somethingElseIdon'tRemember. Perhaps
they're some kind of stale temporary address. Just don't know. But if it's
not a reliable kernel feature, it's of no value to Peter's question.

[my ISP only provides GUAs to their business customers and based on my last
  conversation with them, they have no plans to start]
