Hello,
If anyone upgraded to DHCPCD 5.99.7-r1 and the dhcp server gave ip's based on the MAC address, should know that it send a IPv6 "MAC" (uid or what ever) and they should disable in /etc/dhcpcd.conf the duid option:

Code:

# Use the hardware address of the interface for the Client ID.
#clientid
# or
# Use the same DUID + IAID as set in DHCPv6 for DHCPv4 ClientID as per RFC4361.
#duid


I spent 2 days looking for solutions .. i thought it was my net driver ... but downgrading dhcpcd worked and the config was different so i tried to see if this is the culprit. I think the option should be disabled by default.

In that case, I suggest that you file a bug, the developers are much more likely to see such requests there.

Please read RFC 4361 for why it shoud be enabled by default.
I commented on your bug for this also.
