Here is a log of tracert superuser.com

The first entry (192.168.1.1
) is my router, which does not surprise me. What is weird is the second entry, 10.216.128.1
, which shows even when doing the traceroute from my router or when the computer is directly connected to the internet. My router has a public IP — is my ISP violating the IP standard? Would such configuration prevent me from using the 10.216.128.x
range in my own network?
There is a diagram in an answer to a related question which does not really answer mine — my router knows nothing of the 10.216.128.x
network, and the hop shows even when tracert
ing another hosts on its subnet, which the router should theoretically be able to contact directly:

What is funny is that this private IP does not show up when tracert
ing the gateway:

while tracert
ing an address which is not even in the same network it shows up again, while the gateway seemingly disappears:
