Which is the local DNS listener for systemd-resolvd?

Tbf, it actually looks like it is configured correctly/the recommended way; the stub-resolv.conf you have it linked to right now (from what I can tell by the contents (EDIT: confirmed in the next post)) is the local systemd-resolved dns listener that forwards on to whatever you configured as upstream DNS for systemd-resolvd.
