If the WAN IP address of your router is anywhere within those address blocks, it means your router is not connecting directly to the internet but is instead connecting to another piece of routing hardware.
What we do not want to see here is an IP address like 192.168.0.1, 10.0.0.1, or 172.16.0.1 or slight variations thereof, as those address blocks are reserved for private networks. This is excellent, as it indicates that our public IP address is an IP address that belongs to our ISP. In the above screenshot you can see that the “WAN IP” of the router is identified as 97.*.*.*. Before we get into exactly why that can cause such a headache, let’s look at how you might end up in that situation without even realizing it. Running two routers simultaneously on your home network is exactly the kind of situation where these phantom problems can arise. But what if you start seeing small but annoying problems over the course of several weeks? It becomes increasingly difficult to pin down exactly what is wrong with your network (or what is even causing it in the first place).
If you get a new cable modem from your ISP, for example, and it simply won’t work, that’s an easy problem to troubleshoot. The worst kind of tech problems are the ones that are difficult to pin down.

If you’re running your own router alongside the modem/router combo your ISP gave you, there’s a good chance you’re inadvertently giving yourself a huge headache and a host of difficult-to-pin-down network problems.
