One thing that caught my eye was the zero in your address.  I had never seen someone actually use this...

https://stackoverflow.com/questions/14915188/ip-address-ending-with-zero#:~:text=An%20IP%20address%20ending%20in,addressing%20scheme%2C%20IPs%20from%20192.0.

Do yourself a favor and change you router's DHCP address range... to something normal like 1 or 4 or anything else besides 0.

I got 133 million hits from "ip addresses with zero in it"... none of them good!

No, don't do that. That's quite normal. The modem from my ISP has an IP address of 192.168.0.1 and anything that connects to it is 192.168.0.xxx.

Absolutely 100% normal!

Almost all (if not all) routers provide (by default) this particular IP address in how to reference the home (admin) page of the router itself - This is not a problem at all, however, some people prefer to change this address, to combat spamming and hacking type events, specifically if running a home based web server that is exposed directly to the internet!

I have never seen a router that didn't have that as the default and that includes every telecom provider in Canada.

In networking, there are basically 3 classes of IP address ranges, Class A, Class B and Class C.

The 192.168.0.* basically falls into the class C address range, typically used for home private network addresses, and usually distributed via a home based router with a built in DHCP server to distribute those  addresses within the specified range of the router settings you provide.

The router itself, it almost always set to 192.168.0.1 for convenience and ease of remembrance to access its admin page.  As noted earlier however, it is a good policy to change this default IP address to enhance your security, though, most people just leave it alone.
