I want to note that I mean to use such internal hostnames to reach services inside a VPN. If solutions such as IPsec or OpenVPN can somehow push and manifest host->IP correlations for the OS, as an alternative to pushing an additional DNS resolver living inside the VPN, that would also be a viable solution.

Tailscale is very easy to set up and provides resolvable hostnames (at an OS level) for all connected devices.
