The average person cannot.

Law enforcement almost certainly can.

No. That domain could represent thousands of different people. There's no way
to know who to send your email to.

Okay so u can't find the address of an IP, but when you convert the IP into the domain or ISP can you e-mail there and will the person receive the e-mail?

You can find the location of the ISP, which may OR MAY NOT have anything
to do with the location of the specific IP address.

But as I keep saying, the ISP is as close as you can get. You CANNOT

QOUTE
"how can we recover the ip address even if the profile had been removed from myspace"

Go to Cmd [Command System](Start/run/"cmd") Type netstat -n than Start file transfering with target or camera record. After 2 kb or more of your file or his has been downloaded type netstat -n again, check which IP is missing on first netstat -n you wrote.

If your im goes direct from your machine to your buddies, you can get their ip address by doing netstat -a in a command window. That will show you all the addresses connected to your machine.

People, you MUST protect your PCs with a firewall (the Windows one at the very minimum, but it sucks), up to date anti virus, and spyware software (I like PCTools SpywareDoctor). An unprotected PC on the internet now gets taken over in less than 15 minutes! And you MUST patch Windows and all your applications.

Unless you do all of the above, it is as chancy as unprotected sex.

Me and a bunch of other people have been ripped off by a scammer. The thread is here:
http://www.magictraders.com/ubb/Forum4/HTML/004157.html#12
He was using IP 70.25.65.7 which is in Canada. I am wondering what all steps me and the people that were scammed must take. The paypal account we paid to doesn't have the funds still in it so we can't get our money back that way. How can we find the actual user info for that IP from the ISP and who (being in the US) do we have to contact to get that person arrested in Canada? Please reply by e-mail at least. Thanks! I'm trying to help a group (including me)!

I have a question. Once a lan issues your computer it's IP can a hacker change your IP and your lan not realize this has happened?

Also, how can a person hide their IP address.

Randy: nope. The DNS name and the IP address are, in many ways, just two ways of looking at the same thing. You'll still need the ISP's help.

Dear Leo, I understand that useing a IP address to get the pysical address of a given computer is a problem, as in my case where someone is trying to hack into my computer from an At&t sight in Albq.NM. But what if we have the host name codec? How does a person find a address or even better a phone number to contact that host?,,, for example (83.wl248.albq.attga31ur.dsl.att.net)with an IP address of ( 12.140.248.83 )? Isn't there a way someone could get a pysical address or phone number for that server or host?

What people are looking for is a way to track down a street address - a physical location where the computer in question is located. I will reiterate: that cannot be done by the average user without the assistance of the ISP that is providing that IP address. Of course the ISP knows the physical location - as you say, they have to - but they do not reveal it to just anyone, for obvious privacy reasons.

So the practical answer is, NO, you cannot locate someone physically with only their IP address.

I can not believe I'm reading such, well uninformed, information.

Okay, an IP address is very much like your personal phone number. You have to have one to talk and you have to have one to listen. Just like your phone addy an IP uniquely identifies you, not your isp, not your email server, but specifically YOU (at least a router or computer in your house).

It's simple, the ip address, even with DHCP is used along with a timestamp and you know exactly who you are dealing with (reverse georouting will turn an IP into a physicall address).

So given an IP addy and a Timestamp you know a persons physical location.

IP addresses are like state ID numbers. They are useless to us. They only exsist so that the government can keep track of us for purposes like Bush's spy program. Since people don't want Verachips under their skin (god knows I surely dont want it) they are using the next best thing to invade our privacy.

"The Guy"? Hardly. If your information is correct you've narrowed it down to 65,536 possible "guys". All you did is find an ISP, which does NOT tell you who the individual at an IP address is.

Just to let everyone know that are reading these posts. You can NOT track down who leased the ip address at a specific time unless you have a very good case and an judge orders the isp to give over there logs. Thats assuming that they still have the logs by the time the courtcases are done. If you live in Canada your going to have to have more money then the the recording industrys as they didn't even get the court order. Unless there has been death threats and the police are heavly involved then you will not be able to retrive this data. The only thing you can do is trace the ip to there isp or just compare the ips in the email that you have recived in the past.

Once again, http://arul.telenet-systems.com/track.html will NOT, repeat NOT lead you to a *person*. It even states itself that it will identify the ISP that owns the IP address. If you need to get the *person* who owns that IP, you'll need that ISP's help, which is unlikely.

To find the IP address of someone who just sent you an email, follow the steps listed below:

1. Open your hotmail account
2. Go to Options
3. Be sure that its clicked on mail on the navigation bar
4. Click on Mail Display Settings
5. Next to Message header, choose Full

Now open the email of the person that you want to know there IP address and just above there message(mail) the email should be listed on top of the list. Then to find out were this person lives and some other information go to the website I just gave you in my other post which is: http://arul.telenet-systems.com/track.html
and enter there IP address, then you'll get the person.

I hope that this information will help solve your problems!
Good Luck

You can send an email to the hotmail contact for abusive emails but in reality if the person is not a hotmail user (it is very easy to forge an email) then you are stuck. there is no easy way to find her. you can look at the tags at hte start of the email (you may need to forward it to another email address to pull all the information about that out) but again these tags will only give you a little information to track the person down if they dont know a great deal of how the interenet works. i suggest you search on tracking spam in google and go from there. this will give you information on gleeming the tag information and tracking a user down.

Ok, sorry, I have to throw in my two cents here. The "there's no way to know" is just a stupid answer. You can use any rwhois service to find the ISP who owns this address. Finding out which specific customer of theirs that is using the address is a different matter. However, if a law is being broken then you can go to a law enforcement agency. This gets tricky because of the laws in various countries, what treaties they subscribe to, and to what degree the law enforcement agencies in the various countries involved are willing to cooperate. Most cyber-crime is committed using an ISP that is not in the same country as either the victim or the offender.

This will still usually not yield the identity to you (again, depending upon the country's laws), but the law enforcement will be able to obtain that identity from the ISP in almost all cases (this is certainly the case in the US). If the offender resides in a different country than the hosting IP, then it gets even more complicated.

However, if a cessation of the activity is all you desire, this is often simplified with correspondence with that ISP. Some ISPs do not want their reputations damaged and their entire IP range banned! This is especially true if you are part of a larger media organization and such an action on your behalf would decrease the value of their service and to their legitimate subscribers! In such cases, the ISP simply cancels the offending subscribers account and they are forced to find some other way to harass you.

Now, if their client turns out to be, an educational institution or a business, the offender can be expelled or fired for abuse of IT utilization usage policies (this is nice revenge if you are lucky enough).

All in all, it can be a tedious process (I’ve done it before, in both criminal and non-criminal cases) and it can be very time consuming, can run up a phone bill (make sure you have a good international calling plan) and often results in a dead end. But results can be achieved! It depends upon how pissed this person has got you and how much time you want to spend on it.

Daniel

The whois search in the article will tell you who owns the server. The last server will be owned by the sender's ISP, and you'll have to contact that ISP for any more information. In my experience, ISPs do NOT respond to these requests unless you have a court order.

Help me! So if I have an IP address, there is still now way to find out who owns that? I can trace an email and it gives me servers, but who is that server? I need to find out who is sending me these emails!

I'm no lawyer, but my belief is that it requires legal action ... something like a court order ... for the ISPs to divulge that information. I know of no way a hacker could get that info, short of hacking the ISP's own databases.

The address you goe was the address of the ISP that owns that IP address. It is NOT the address of the user of that IP address. That information can only be had with the help of the ISP, which they are typically NOT willing to give.

Unless you use a "direct connect" functionality that's available in some IM clients, you *don't* know the IP address of the person you're chatting with. All communication is with the IM service's server.

Hey ben, it is very possible that they can figure out your IP Address and where you live and stuff like that. People make programs but dont sell them and stuff they put them up on sites for downloading. whoever looks at the site and downloads the files, they can use it to find out anything about you. trust me.

You cannot tell who owns an IP address, only the ISP who owns the IP address. No one person every owns an IP address. It is leased for a specified time period. If something unlawful was done, then contact the abuse@*** address for the ISP(Don't bother with KORNET, they dont reply to anything, they are the Korean Government's Manager for IPv4)... Stop asking "how do I find out who owns this" It sounds as bad as asking "How do I find out someone's IP address"... For the most part, if you need to ask, you dont need to know...
