    The best that a non techie person could do would be, to be able to trace your IP address which could give you the city/town where the computer is. Hackers maybe able to get a little closer, but to narrow it down I believe the help of your IP is needed, and they won't/shouldn't do that unless ordered by the courts/police. Where ever you go, you will leave a trace of your IP address, this is usually available to administrators of sites that you visit. They can then trace your address if needed ... we do that here if it's spam or someone is not not acting in a responsible fashion. For an example, I've traced your IP address and it shows that you are not from Switzerland .. for your privacy, I will not say where.

    Having said that, I noted awhile back that a University here in Canada had developed a system that kept track of the students computers and could pin point where it was within about a fifteen mile radius of the campus. Nowadays, incorporating a GPS type system in a computer would zero in to within feet or less of its location. This technology is here, and doesn't even need the Internet to do a trace.

    I'm not a pro in this area, so I'm sure if there are other members who know more on this subject, they will give you their answers.

    Hope this helps.

    In theory yes.

    A technique called remote physical device fingerprinting could identify a single laptop by it's unique electronic fingerprint when connected to the internet (things like cpu tolerance are what are used to identify the machine, not any particular piece of hardware or software installed).

    Once it has been identified, tracing to the IP address is the easy part. And then a physical address can be obtained from the ISP if there are legal grounds for them to provide this information.

    Also I have not checked but I would imagine software exists that can be installed in laptops should they be stolen, that "phones home" so that is another consideration.

    They do have programs that can track a stolen PC

    It is called "lojack"

    thank you very much , i think that's the way they can easily find you by connecting the laptop to the internet , identifying the CPU and easily by tracing the IP adress by ISP

    i think my question was a bit amator , thank you very much for your help

    Default How to read an IP

    Hi.
    Excuse me for being out-topic maybe.
    But I have a similar question:

    How to read a user's city/town from the IP address?
    (or should I start a new topic?)

    I mean not to pin-point a computer's location.
    I don't need to, or have no right to do so anyway.
    However, it will be interesting to know where the people come from,
    for example, those communicating with on e-mails.
    Turn on 'details header' in setting/option can show the IPs.
    But there are just numbers, not even telling their counties.
    I'm wondering if there is a place to read the codes(IP)?
    Like a dictionary something?
    Thanks.
    Ni hao!

    There are lots of services like this one:
    http://www.ip-adress.com/

    But they are a bit hit and miss depending on lots of different factors. Often they will pinpoint the location of the isp rather than the person, so can be hundereds of miles out (no bad thing in my opinion).

    Useless for email as well because it will just point you to the email server the person was using. So it going to be the ISP again or yahoo mail, gmail etc.

    That is exactly what I am thinking of!
    Thank you.
    I think it's good enough,
    as people's location should be close to their ISP.

    Moreover,
    I think it works on e-mail as well.
    I've just tried to send myself a test e-mail,
    among those IP addresses showing in the header,
    one of them is mine(can show my city).
    I also checked a friend's mail who is living in London,
    ...... and yes they(she and her mail) are there.

    I think it's a good way to confirm one's identity.
    Because I heard/think that an e-mail address can be fake,
    while an IP address couldn't be,
    right.
    Ni hao!

    Hi ehsan83

    I think Canuck's program must have had a bad day...

    I don't think I am giving any secrets away (as you have confirmed you are in Switzerland)

    Your ISP is sunrise.net

    & Z├╝rich ? Ruemlang, Switzerland is most likely the region ?

    No-one has mentioned a GUID (Globally Unique Identifier) or UUID (Universally Unique Identifier)

    GUID > http://en.wikipedia.org/wiki/Globally_Unique_Identifier

    UUID > http://en.wikipedia.org/wiki/UUID

    If you want to know more about how these can identify a single computer on the net, do a google search for GUID or UUID
