Traceroute showing 5 internal hops before ISP network

Routers Cellular, USB modems

This is a traceroute using my GL.iNet GL-X750 with latest firmware.

Why are there 5 internal hops using the private address space before it hits my ISP network?

There is no VPN or Proxy setup.

Tracing route to portal.unidenvoice.com [103.135.87.3]

Looks like the CGNAT routes

Thanks but the same traceroute to the same ISP using a different router/connection (Telstra FTTN) does not have these. Are these used for 4G connections to Telstra’s data network?

Does your FTTN/ISP modem own a public IP? If so, it definitely has fewer hops.

You can learn about CGNAT
