Any update? I'm still seeing failures to bind to an IPv6 address that systemd-networkd has previously reported as being up. I can insert an arbitrary 5 second pause as a workaround, but this should not be necessary.

I am testing oracular / 24.10 , and I bind some services to specific IPv6 addresses. In order to wait until the IP addresses are up before binding to them during boot, I use systemd-networkd-wait-online, modified to wait for IPv6. The problem is, despite systemd-networkd reporting the IPv6 addresses are up, binding to them still fails when the daemons attempt to launch. If I manually start the daemons after boot, they launch fine. It would appear the system is reporting IPv6 addresses as available before they are ready to be bound to by applications, therefore causing those application to fail during boot. Log attached.
