Your IPv6 host can (and usually does) have several IPv6 addresses at a time. Disabling the use of randomized identifiers ensures that one of those addresses is an EUI-64 address. But the privacy extension are still enabled (this is a separate option, "netsh interface ipv6 set privacy state=disabled"), and your host will additionally have temporary addresses that expire & change over time and are used
for outgoing connections.

Thanks for the pointers, now I'm able to correctly get an IPv6-address
that should work with ra-names. However it seems that dnsmasq doesn't
have any hostname in the DHvPv4 lease file.

$ cat /var/lib/misc/dnsmasq.leases
1482365715 3e:XX:XX:XX:XX:02 192.168.1.184 * 01:3e:XX:XX:XX:XX:02
1482334524 00:YY:YY:YY:YY:67 192.168.1.133 hostname *

Well, dnsmasq needs to get the hostname to assign to a machine from someplace. I don't know all the possible places (search the manual page for that), but I can think of:

  1) Dnsmasq configuration (dhcp-host options)
  2) /etc/ethers if enabled
  3) suggested with the DHCPv4 request by the client

I think Windows 10 should suggest a hostname (3), at least it seems to do for me. I have manually assigned
a hostname on the Windows computer, and dnsmasq knows and assigns it.
