Continually fires onReachabilityChanged when on IPv6 only network.

[loganblevins]

When testing for IPv6 compatibility, I noticed that Reachability got in the way. Our logs indicate that reachability is firing multiple, continuous callbacks when on a test IPv6 network.

Reproduction:

1. Setup a NAT64 network (IPv6) through Internet Sharing on your Mac.
2. Disconnect iOS device from all networks, including cellular.
3. Connect to this shared Wi-Fi network from an iOS device.

Expected Results:

Reachability should only fire once, on the initial instantiation.

Actual Results:

Reachability fires multiple, continuous callbacks indicating that reachability has changed, when it has not.

I got the same issue. I suspect the AF_INET need to change to AF_INET6 to support IPv6 network.

Please confirm. Many thanks

I'm using Reachability.swift 4.3.0 and swift 4.2 , is it works on IPV6 ?
