[erlang-questions] How does running nodes() on host knows about all connected nodes?

[Harit Himanshu]

That is very interesting to learn. Thanks a lot for explaining this to me.

The follow up question then becomes, is it recommended to have such a mesh?
(because I read word problematic). How do people in general connect to
server? so they start with *-connect_all false* as mentioned?

Thanks
+ Harit
