NetworkPinger

NetworkPinger is a utility for testing connectivity to an IP address. It sends a series of ICMP pings to a given destination. If any of them fail, it will invoke a failure callback with the reason for the failure. If they all succeed, it will invoke a success callback with the average round-trip time of the pings.

NetworkPinger is primarily intended for in-game server lists, where you want to see whether you can connect to a server and if so what your ping is.

Note: IPv6 addresses are currently unsupported due to a Unity bug. If and when that's fixed I should be able to add IPv6 support.

Example usage

public void LogPing(IPAddress pingThisAddress)
{
    var pinger = new NetworkPinger(pingThisAddress);
    pinger.SendPing
    (
        onPingSuccessCallback: success =>
        {
            Debug.Log($"Ping to {pingThisAddress} succeeded; average round-trip time was {success.AverageRoundTripTimeMilliseconds}ms");
        },
        onPingFailureCallback: failure =>
        {
            Debug.Log($"Ping to {pingThisAddress} failed; {failure.FailureReason}");
        }
    );
}

You can also pass the function custom values for the number of separate ping packets to send and the timeout for ping failure.
