IPv6 no configured subnet contains IP address

[SMHRambo]

Since version 5:29.0.4-1ubuntu.24.04noble i get this error for multiple networks.
Version 5:29.0.3-1ubuntu.24.04noble works fine.

Error Message:

I can confirm that we are also impacted by this issue. Our host OS is RHEL 9, and this problem exists with docker-ce-3:29.0.4-1.el9.x86_64. However, downgrading to docker-ce-3:29.0.2-1.el9 bypassed that problem for now.

Our setup involves a docker network with the ipvlan driver. So this problem seems to impact both ipvlan and macvlan driver.
