Is this a double NAT issue? Traceroute showing multiple Private IPs
When I run a traceroute to any website, the first hop shows my Xfinity gateway's IP address but the second hop lists 3 more private IP addresses beginning with 172.20.42... I'm confused as to why there are several different private IP addresses within the first 2 hops, since I only have one Xfinity XB8 gateway.

Well not sure what is going on but if you have 2 routers that would indicate a double nat. you can go into your router and look for the WAN IP and see if it is as public address or private address.

I only have the Xfinity XB8 gateway and don’t have any other router, which is why I am confused about the trace route results. I just used the admin tool to check the WAN IP address and it is a public IP.
