Ok so I have noticed when going on porn sites that many times they have things like "find hot bitches in [insert your city here] tonight!!!!" I decided long ago that my city isn't the hooker capital of the world, so I am wondering how the websites can tell where i live. Can anyone enlighten me as to this knowledge?

If I had to guess, (and basically that's what I'm doing) I'd assume it's based off your IP address. My reasoning for this is, try going to the same sight with proxies located in other area's, and the ad's will be targeted for that area. Adult Friend Finder is notrious for this sort of thing.

Your IP address gives away a ton of information such as what city you are in.

It says Marlborough for me. Which is weird since I'm in Midtown Manhattan.

It does a whois and puts up the town of the isp it belongs to (more or less). Source code at:

but my hosting provider seems to be having problems right now.

"How is geolocation done?
Determining the country from an IP is relatively easy -- the IP registrars supply the information for free. Whenever an IP range is allocated, it is allocated to an organization that needs to supply their country when they register.

Determining the city from an IP is more difficult. One way would involve looking at all the IPWHOIS information for all IP ranges. This produces information that is not very accurate (an ISP covering an entire country may have all IPs registered to the same city), and may violate IPWHOIS agreements.

However, several organizations have found ways to more accurately determine the city of IP ranges. This is typically done by partnering with websites where users enter a city or ZIP/postal code (often when registering or ordering something). By looking at what IP ranges belong together, it is often possible to determine the city for IPs even if no information is known about that specific IP."

your sig says that the city is not foud, but under the host name, it gives me "pcp0311004pcs.venice01.fl.comcast.net" From that it would not be too hard to determine that I am in Venice, FL. The porn sites say 'sarasota' to me though. They probably get that from a traceroute.

Mine shows Ogden, UT. Eventhough I'm 925 Miles away (near Omaha, NE). But then again I'm at a truckstop and their HQ is in Ogden! Edited by Clembo

From my experience the ISP you are using dosen't usually reveal the city you are actually from. According to your sig I'm in Denver, and according to IRC a lot of the time I'm in Florida, but occasionally it'll be right. They could also do a tracert and analyze that, but I don't see why pr0n sites would put so much work into that.

ShowMyIP.com and the infamous Adult Friend Finder sites get it more accurate. What database or WHOIS server do [i]they[/i] use?

I found out they use a database. No special WHOIS queries, no time-consuming traceroutes (why would anyone think they used these??), but a very expensive ($450! LOL!) database. Here's a free sample: [url="http://www.ip2phrase.com/ip2phrase.asp?template=I+AM+A+NIGERIAN+THIEF+WHO+WILL+KIDNAP+YOU+FROM+%3CCITY%3E,+%3CREGION%3E+IF+YOU+DO+NOT+PAY+%24419,000+TO+ME%21%21%21%21"]click here[/url].

Ok I don't know java so could anyone explain this to me:
[code]<script language="JavaScript">
<!-- // Start of AdSubtract JavaScript block; you can ignore this.
    // It is used when AdSubtract blocks cookies or pop-up windows.
document.iMokie = "cookie blocked by AdSubtract";
document.iMferrer = "referrer blocked by AdSubtract";
function iMwin() {
this.location = "";
this.frames = new Array(9);
this.frames[0] = this;
this.frames[1] = this;
this.frames[2] = this;
this.frames[3] = this;
this.frames[4] = this;
this.frames[5] = this;
this.frames[6] = this;
this.frames[7] = this;
this.frames[8] = this;
this.length = 0;
}
// End of AdSubtract JavaScript block. -->
</script>
document.write('I AM A NIGERIAN THIEF WHO WILL KIDNAP YOU FROM [edited out city], [edited out state] IF YOU DO NOT PAY $419,000 TO ME!!!!');[/code]

Also does anyone know how being able to obtain info from the ip can be defended against and could explain?

edit: also could anyone show how I would get that information and send it to a log file? Such as if someone visited a website it would log their ip, location, OS, ect and send it to the log file. Edited by Dr. Z2A
