** Description changed:
Hello,
Let's first list my configuration items:
* apache2 2.4.29-1ubuntu4.14
* release: Ubuntu 18.04.5 LTS
Upon reboot, the following message is seen in apache2.service logs:
-- Unit apache2.service has begun starting up.

The apache2 configuration is using the ipv4 and ipv6 present on the server:
/etc/apache2/ports.conf:Listen :443
/etc/apache2/ports.conf:Listen :443
/etc/apache2/ports.conf:Listen [REDACTED IPV6::33]:443

- and the /etc/network/interfaces look as this (no netplan):

So I was wondering if the "ifup@bond0" was enough as a dependency here,
to be sure to have the ipv6 up and running or if we would need something
like "ifup@bond0:2" and "ifup@bond0:1" as part of the list of the
services in the network.target "After" list.
