Purpose of protocol and port specific AirVPN DNS servers

[sherlock.holmes 3]

Here: https://airvpn.org/specs/ is stated that each AirVPN server has its own DNS server. Why is that? Why are the DNS servers protocol and port specific? Why not give just one? Is that arbitrary or does it serve a purpose besides load balancing? What will happen if I use for example UDP Port 53 for my VPN connection and 10.9.0.1 as my DNS server instead of the listed 10.8.0.1?

This will still work.

Staff explained it somewhere around here years ago, all these IPs point to 10.4.0.1. Why? No idea anymore. :/
