Why is tracert not showing my public ip address?

Super User Asked by sssss on December 20, 2021

Tracert does not show the IP of my WAN interface, not the gateway also. My public IP starts with 37 and it does not appear in tracert.

One Answer

Traceroute results correspond to whole routers, not their individual interfaces. Even though a router has multiple IP addresses on various interfaces, it will always produce only one trace reply.

When doing so, the router will usually send that reply using an address from whichever interface the original request arrived through – in this case the LAN interface.

(This means that running traceroute between the same two hosts in opposite directions will show different IP addresses for the same routers.)
