It's specifically said the router's firmware was encrypted so he couldn't read it, much less install sniffers or backdoors.

And yet he managed to emulate it on his home network to avoid breaking the law by hacking an actual router belonging to the city...

Some other things don't add up: The hacker connected to it and checked what his IP was, using http://whatismyip.com./ This way, you usually find the address of the router that links you to the internet. ... an actual hacker has many faster and more reliable methods of finding the router's IP at their disposable, that don't involve asking remote websites what your IP address is and guessing based on assumptions of how the network owner might have allocated their addresses.

It is the only machine on the network that uses that IP.

ON A WIRED WORKSTATION ON THAT NETWORK, go to http://www.whatismyip.com/ and see if the IP address it reports ends in .157.

ON A WIRELESS DEVICE ON THAT NETWORK, do the same.

This will tell you whether a machine on your network may be sending spam from the same address as your email server.

I'm curious how you can get an IP address with a bit of js.

Perform an AJAX "get" on http://www.whatismyip.com/ or any other IP lookup site.

*This is based on the assumption that the average Windows user is, in fact, a chimpanzee.

This is a valid assumption. The other day, I asked my mom to go to http://www.whatismyip.com/ because she had just reconnected the Internet (dog kicked out the phone cord) and I didn't want to wait for ddclient to update my IP, and she gave me an IP. I pinged it, and it said "PING crawl12-34-56-78.googlebot.com (12.34.56.78) ...". She put the address in to google and read me the search result instead of going to the site.

Depressingly, you're probably right that pasting into the address bar is far, far beyond the level of knowledge of the average user.

I was banned almost a year ago and AFAIK that ban hasn't been lifted. We are banned couse my ISP use transparent proxies. And slashdot thinks that it get a lot of connections from the same IP.

There are places like whatIsMyIP that detect both, my proxy IP and my own IP. I think that's should check for my real IP, no my proxy's.

Plus, it depends on how well they go about presenting the page you arrive at. Take a look at whatsmyip.com (notice that this one lacks an "i" ie. not "what is my IP" but "what's my IP"). Prettly slick page, context sensitive and all. I bet this one gets more clicks on those links all over the place than that single hosting ad that runs on whatismyip.com.

If you browse through the p2p cache, it also hides your IP address.

Check this out: Normal browsing and Coral browsing.

I found myself in this exact situation once a while back. And when I'd call the ISP I'd usually be on the phone with "tech support" people who didn't even know what an IP was. After a lot of frusteration from not having a real IP, I later discovered that I actually _did_ but it was behind a 1:1 ratio NAT built into the ISP's modem device. I went to http://www.whatismyip.com to discover the public IP that my destinations _thought_ I had, tried to connect to it from an off-site host, and it worked. Maybe you've already tried this, but if you haven't it might be worth a shot.

Head over to http://www.whatismyip.com It's already done...

Well I've got anti-anti-anti-spam software. I know all about you. You can't hide from me.

http://www.whatismyip.com works for me ;)

Been there, done that :) (But different environment, corparate job using VNC.) Here's another way of doing it:

"OK, Open up Internet Explorer. Type 'whatismyip,' all one word."

This takes them to www.whatismyip.com, a site so trivial, it's funny. But it's useful and it definitely serves a purpose.

It's even worse if they're running 2000/XP and you need to guide them through using ipconfig from the command line - oy.

If you want to find the IP address of a transparent proxy, simply point your web browser at a web page that will print out "your" IP address when you request a web page. Instead of printing the IP of your firewall or your host, it will print the transparent proxy's IP address.

For example:

• http://www.whatismyipaddress.com/
• http://www.whatismyip.com/
• Google Search for "my ip address"

After that, you may be able to do some more investigation into what kind of host it is and/or what kind of software it is running. (This is left as an excercise for the crac...err, reader.)
