Is it possible to see 2 or more routers connected in series in tracert?

Question

Computer networks

If 2 routers are connected one after the other, will it be visible if you run the tracert command? I see that the first hop is the address of my router, if someone connects to my line (we have authorization only by poppy and you can easily find it out just by plugging my cable into your router as I understand it) I can see it in the trace or I need to use another way?
I must say right away that the network with gray addresses is 10.x.x.x and on the router I see that one of them comes to the interface, but the router can be configured as you like. Will the router be visible except for mine during tracing?

Answer 1

Traceroute is not magic. it shows only the information that the devices themselves on the route told it.
Usually all layer 3 hops are visible. But you can build a VPN somewhere on the route that will go around the globe a couple of times using hundreds of intermediate nodes, and traceroute will show it as one hop, because the VPN is layer 2.
In general, depending on the type and settings of intermediate nodes, they can either show up or not show up.
And it may also be that the host ignores ICMP packets altogether (or filters them, responding only to selected ones), and traffic through such a host goes, and when you try to ping or trace, only silence or asterisks.

Answer 2

tracert performs normal pings (ICMP echo request) with a gradual increase in the TTL value of the packet from 1 to max hop.
On any gateway/router, firewall rules can block ICMP. Then on that hop, tracert will show * instead of normal statistics.

Answer 3

If you mean that the second router is connected as a client, then no. It's easier to look at the dhcp table in the router interface.
Or is it assumed that the router is BEFORE your router? In a cut? Then yes
No, the poppy cannot be recognized by connecting your cable to another device. If we are talking about the poppy address of the WAN interface

Answer 4

The author clearly indicated that the routers are connected in series.
Yes, both routers will be visible in the trace under normal normal conditions.
