Hi, Ipconfig lists the default gateway and subnet mask. But what should be done to know the inner address of the gateway, sub gateway etc of the ISP.
              to put it simply, how to know the inner dns address of the router. I forgot the admin user and password. what this nslookup do. If i use the command at cmd, it lists unknown and give my router page ip correctly. Is there any problem . How to rectify this error server unknown, and gives the correct ip of my ISP gaeway

Boggin:
nslookup won't help you with that.

If it's an ISP supplied router then the default username and password will be on the router somewhere.

You will need to factory reset the router usually by holding a needle or a straightened paperclip in a pinhole on the rear of the router and log in with the default names after it reboots.

Hi, Boggins , i know but i had to reconfigure it. I have lost the user name and pw, but now it is working. I asked for a way to know the things. When hotstar asked to click a link , it gets those data from my router .Why nslook gives server unknown message. What is the real purpose of having that command.
                                   When i click that link, all those information from the router , with strong pw and user name, which even i fail to note it, (Hard disk failure and replaced) are given.
                                    There should be some software to know these things.

Hi, no reply so far

Samson:
J, I'm not really sure what your question is here?

If it is how to get your router's admin/ password details if you have forgotten them? Try this, it works for most Netgears anyway.

I assume/ hope that you have made a backup of your  router's settings? If not then do it. This should be saved as a .cfg file, at least it is with Netgears. Then you can open the .cfg file with notepad and search for the admin username and password for your router there. It most likely will not be true for all brands of router but worth a shot.

Easiest way is a post it/ sharpie on the router itself  :wink:
