Anybody know if it's possible to get the IP address of your router without accessing it?

And we have to assume that you cannot route with the computer so you can't go to a website to get the IP address from there and of course ipconfig /all is only returning the IP address assigned by the router, not the internet IP address.

Big thanks to anyone who can find an answer, found one thing on net saying something about "ping -r 1 www.awebsite.com" to get the IP but that was a bust.

Uum, I think he said "you can't go to a website to get the IP address from there" Smile

medeirosm, i don't thing that's possible. Maybe you could get IP over UPnP if you write a program or something, not sure tho..

I wasn't sure if it was possible either but if I figured it out I would be a hero at work cause I do technical support for an unnamed ISP <cough>Verizon<cough> and having to reset someones modem/router because they forgot the password just t check if their getting a valid IP address is a real pain.

I'll continue to search, I just figure if a website can pull that IP why can't I pull it from the DOS prompt? Confused

When you go to a website, it's your router that sends request (hence, the website server knows your external IP). When you query your router locally there is no outgoing access..
Just look at some programs that use this technique to get your external IP address (fe FlashFXP or Bulletproof FTP Server). They all query their servers to get external IP.. BitComet is only program that I use who doesn't connect to his server to get external IP but uses UPnP, so that's why UPnP is probably what you're looking for... Hope it helps Smile

Well thanks for pointing me in the right direction.

I talked to Linksys and they say it ain't posible, but i'll keep fighting the good fight, there's gotta be a way... Smile

There isnt, your on different subnets and cannot route to each other without going through the router, which you don't appear to have access to.

You dont need their IP to know they are connected, if you run a ipconfig /all it will list DNS info that tell you an outside connection has been established.

Also like you said you can ping a certain internet IP, or run a tracert to almost any IP with a hop count higher then 2 and it will start jumping outside your network to the ISP's servers.

It wont give you your IP but it will definitly prove you have an outside connection and thus in fact do have a unique IP. But then again if you do have such a connection I suppose you could just open up the browser and it would work...so the real question is, why do you need to know the IP so bad? Smile

Well let's say there is an outage in Baltimore, MA and the sympton is customers cannot route but they have sync and can authenticate with the Verizon servers, I need to make sure they are connected with a valid IP address before I can be sure they are affected. Otherwise you need to reset the modem/router, set up a new connection, then check for valid IP - makes a 2 minute call a 15 minute one.
