Today I fumbled thru the install of Rayfish and Yggdrasil. Both are awesome, but Rayfish was so much easier to install and use.
Have you tried these yet?
Here’s the Yggdrasil link:
https://yggdrasil-network.github.io/
Yggdrasil has Android, Windows, Linux, Apple installers.
Rayfish only works on desktop right now, but hopefully soon they will be able to get it on Android.
https://github.com/yggdrasil-network/public-peers/blob/master public peers were probably chosen because they are always online, and probably high performance vps which you can set in your config file.
but maybe this https://yggdrasil-network.github.io/2018/07/28/addressing.html is a better answer to your question
