Windows only uses the first two IP addresses from clients.conf?

FelixJacobi commented 4 years ago

Hi,

I tried to assign several static IP addresses via DHCPv6 to a client using this entry in a clients.conf:

[client_4]
address = fda9:b38a:2445:1001::4 2001:470:539f:1001::4 fda9:b38a:2445:1001:921b:eff:feac:c691 2001:470:539f:1001:921b:eff:feac:c691
class = default_enp3s0.1001
hostname = vm-server
mac = 90:1b:0e:ac:c6:91

It seems that Windows just uses the first two entries from the address list (the one ending with ::4).

If I swap them with the two other ones, these one are used instead. Has someone seen something similar? Could this be a limit like in macOS which only accepts one IPv6 address via DHCPv6? (I researched but didn't found anything pointing out that)

Can you make sure that all addresses have been submitted to the client? Logging the session with Wireshark on the client could give more insights.

Hi,

I didn't have time until now to investigate using Wireshark. However, an ISC DHCP client on Debian 10 in the same network works fine and receives all addresses configured in clients.conf. So I think at least the network is probably fine. I will take further investigations in the near future.

I never used more than 2 addresses for Windows clients so if this is a bug or a feature of Windows it never came up.
