Why default IP addres couldn't be access

I bought a new Netgear router. At the time of the router set up, I entered the default IP address But sometimes after I noticed that it didn’t access the default IP address. Why this has happened? What should I do?

Hi Alice. Can you give a little more info for me? The IP you’ve noted there is your router’s local IP, and not public IP. Are you trying to monitor a node? What are you attempting to do, and how far have you got?
