February 28, 20242 yr Our ISP will assign a new ipv6 prefix for the home network periodically, and also do it when the router restart. Every time the prefix changes, From dhcpcd log, Unraid will set the route to right value but won't update its own ip. I have to restart the unraid server as a workaround. Any approach to prevent it? I'm using 6.12.6. I tried both SLAAC and DHCPv6 for my router and none of it works for unraid, while the other systems (Windows and Debian) works well. The diagnostics is attached. tower-diagnostics-20240228-2308.zip Edited February 28, 20242 yr by Mr.win7 add extra info for network config

March 12, 20242 yr Community Expert I've asked @bonienlto take a look when he can, since basically only he can help, but he has been unavailable lately, so you may need to wait a little longer.

Thanks JorgeB and bonienl! I've suffered from the issue for a really long time. The behavior about IPv6 was changed for several times and it become worse each time(sigh
April 18, 20242 yr Same issue here. Unraid does not pick up the latest prefix from RA. This dynamic prefix shit for private customers is a pain... Edited April 18, 20242 yr by KluthR
April 21, 20242 yr In current .10 release I also see permanent DHCPD6 renew messages, didnt remember the exact term, hold on… dhcpcd[1128]: eth0: requesting DHCPv6 information every ten secs. But maybe its because I habe only Stateful RA enabled router?
April 21, 20242 yr Community Expert my router does ipv6 porperly. but here is the corect command to release and renew form termainl ipv6 address. Tested: ip -6 addr flush dev eth0 ifconfig eth0 inet6 0 Replace eth0 with the interface you need to have renewed. In my case it vhost0 so eth0 becomes vhost0 Edited April 21, 20242 yr by bmartino1

April 27, 20242 yr Author Hi @JorgeB and @bonienl, could you please share us the progress or plan about the issue? Though we can manually flush the IPv6 address, I still want the Unraid to flush it automatically.
April 27, 20242 yr Community Expert Bonienl has been unavailable, I expect he will look at this as soon he can after that changes.
August 19, 20241 yr Community Expert Can anyone please confirm if this is still an issue with v7.0.0-beta?
July 1, 20251 yr I've just encountered this issue with unraid 7.1.4, rebooting router means I get new ipv4 and ipv6 addresses, although on unraid I have fixed ipv4 the ipv6 address is given by the router, I ignored the issue overnight to see if it would correct its self but it did not.I tried:ip -6 addr flush dev br0 ifconfig br0 inet6 0but ifconfig did not work, so i was forced to use:nohup bash -c "ifconfig br0 down && ifconfig br0 up" &It would be nice if unraid could periodically renew the ipv6 lease when in this configuration to ensure is it updated after router restart
