This problem is **not** specific to `worker40.oqa.prg2.suse.org`. It also leads to failing alerts that have been silenced for now: https://stats.openqa-monitor.qa.suse.de/alerting/silence/444a55a0-8fce-43fd-8a85-50c817d0f46d/edit?alertmanager=grafana
## Acceptance criteria
* **AC1**: The mentioned silences are no longer necessary necessary.
* **AC2**: We still have alerting for reachability of those hosts (maybe only for IPv4, in the best case the underlying problem is fixed)
## Suggestions
* Work with Eng-Infra to make AAAA records and DHCPv6 work
* Remove workaround from openqa-salt-states after IPv6 problems have been addressed fixed).
