Summary

Hi,

We are in 2024. All plane component are listening on 0.0.0.0 instead of [::]. Unable to use the app on a dual stack kubernetes cluster because of probes is using IPv6 by default. I don't want to do custom builds anymore to support IPv6 as every updates break my install and I have to re-install a fresh plane chart. Please support IPv6 by default or use a environment variable for the listening IP.

Thanks in advance.

Why should this be worked on?

We are in 2024, not supporting IPv6 by default is quite strange and shameful.
