Some Search clusters have inconsistent AAAA DNS records for the primary IPv6 of the hosts
Open, HighPublic

Description

Some clusters managed by the Search team have inconsistent AAAA DNS records for the primary IPv6 of the hosts. Some hosts have the AAAA record in the DNS for their primary IPv6 address, some don't.
See https://wikitech.wikimedia.org/wiki/DNS/Netbox#Mixed_clusters for more details about the possible risks of the current setup and the two alternative actions to move forward.

This is the list of the affected clusters and related hosts as of 04/07/2022:

  • wdqs*:
    • have the AAAA record: wdqs[1014-1016,2009-2012]
    • lack the AAAA record: wdqs[1003-1013,2001-2008]
  • dumpsdata:
    • have the AAAA record: dumpsdata[1004-1007]
    • lack the AAAA record: dumpsdata[1001-1003]
  • snapshot:
    • have the AAAA record: snapshot[1011-1017]
    • lack the AAAA record: snapshot[1008-1010]
