Amanah Tech is a provider of colocation and dedicated servers. Some of AirVPN's CA servers I think are hosted by Amanah. And Private Layer is the data center of Virginis (CH). So the rest are likely AirVPN server providers, too.
As Eddie is pinging all the servers constantly to determine, well, your individual latency to them, you are right that the "culprit" is Eddie.
Now, keep in mind that AirVPN server IPs are shared IPs, shared with hundreds of other clients. They might be flagged because there could be people using the VPN who are oblivious to the fact their computer/network is part of a botnet (or they know full well that they are…).
In any case, it's got nothing to do with your own network, but I applaud the effort to try and find out more. Keep at it.
