Pingman Pro V5.11.5.5106
ISP Cogeco.ca cable 120Mbps.

The first hop alternates between 182.168.0.2 (named puma7-atom.cogeco.local), which I presume is my modem's address, and 10.75.224.1 (unnamed).

The second hop is also 10.75.224.1. As you will see, it looks like a ping is not shown from 10.75.224.1 on Hop 2 when one is received on Hop1.

Can anyone explain why this is happening?
