I'd guess your provider is using 192.168.1.1 private address for his router internal addressing.

But he should apply some filters and not respond from this internal addresses to Pings from his customer devices.

Your ISP would be ATT or Comcast would it ? :)

Assuming that your ISP has used private address space 192.168.1.1 on some interfaces (which they are probably NOT advertising to you) and assuming that you do not have a route for 192.168.1.1 inside your network, and assuming that you have a default route configured which directs all traffic to unknown destinations, then this scenario makes sense. You send ping and traceroute packets to the ISP, the ISP knowsd how to get them to a device which has used that address, the device generates a response, and the ISP knows how to route the response back to you.

So it works. Perhaps it is unexpected. I do not see that this is a problem.
