This PR, we added -4 and -6 options to redis-cli to determine IPV4 / IPV6 priority in DNS lookup. This was mentioned in https://github.com/redis/redis/pull/11151#issuecomment-1231570651 For now it's only used in CLUSTER MEET. The options also made it possible to reliably test dns lookup in CI, using this option, we can add some localhost tests for #11151. The commit was cherry-picked from #11151, back then we decided to split the PR. Co-authored-by: Viktor Söderqvist <viktor.soderqvist@est.tech>
