IP Address location? Shared IP's?

    I recently traced my IP address using one of those geotool add-ons to firefox. According to that, my system is in cork (http://geotool.flagfox.net/?ip=92.251.255.15&host=92.251.255.15). The problem is that I am in Limerick! Not near the Cork/Limerick border either!

    I have 3g hutchinsons internet and I heard somewhere that 3 only have so many IP addresses and that multiple users work from one IP. Is this true? If so what repercussions can this have on me? Is the fact that this site thinks I'm in cork because someone there shares my IP?

    Lets just say someone who shares my IP address watches child pornography and a federal investigation is launched in America, could I end up getting the blame? What is the story with these shared IP's? Should I be weary of them?

    Thanks in Advance,
    Jackobyte.

    Geolocation for an IP address is very very unreliable, even when you have a unique IP. Some people will be living in the middle of a river. It has no implications for you, except if someone does something to get that IP banned from websites or services (for SPAM, being a muppet, etc) and then you can no longer use those services.

    Shared IPs are used by crap ISPs, like Three, because they can't be bothered to set it up correctly.

    But can someone else be using my IP address? Can it lead to implications for me? Is there anyway to avoid this?

    Remember, when your trace an IP your tracing to the external IP address that your ISP is assigning to you. So this address is registered to them - not you. The IP range is registered to their location not yours. They will have a data-centre in Cork assigning out a range of IP's.

    For example I can trace mine right now and it will trace to Dublin, but I am in Limerick. But that is because BT Ireland's data centre is in Dublin.

    With 3 yes, lots of users share an ip causing problems

    It's not your IP address, it's the one Three uses for all of it's customers. The only implications are those I mentioned previously.

    If you're worried about legal ramifications, then you're not going to be prosecuted on an IP address only. It wouldn't be just you anyway, it could be thousands of people at the same time.

    It couldn't be one address for all 160k 3 customers seeing as there are only 64k IP ports for the return ( minus the 1k well known ports)

    Surely they must have at least 3 public IPs .

    OK, not one for all of them, but many users anyway. It may be as many as 6 IP addresses...
