cloud-init is performing DNS queries to *random* domains such as does-not-exist.example.com and example.invalid

Description of problem:
cloud-init is performing DNS queries to *random* domains such as does-not-exist.example.com and example.invalid upon the start to verify the DNS redirection is configured.
Either environment with IDS or without DNS server configured this might be issue as when doing a lookup it might be flagged as potentially suspicious or causing timeouts, which can lasts hundred of seconds.
Version-Release number of selected component (if applicable):
restart VM check for the DNS requests.
We are looking for a patch that would possibly disable the function by setting the empty list during the checks.
