IP address questions

[shotcaller6]

You can download IPnetInfo (free) and once you have the IP address you want, that you obtained from the email header, enter it in the IpNetInfo program and it will resolve the issue of who and where they are originating from, complete with address and phone contact info.

Call the cyber police and tell them to backtrace it.

That the ISP registered to that IP block. I guarantee the ISP is not going to give up subscriber information without a court order.

They will if you work for the government.

No they won't. They will tell you to come back with a warrant.

You will need to look at the SMTP headers in the email itself to determine point of origin, which SMTP servers it passed through, etc. Without the headers, there's not much you can do.

Once you have determined the point of origin, whether by IP address or by FQDN, you can look it up online via ARIN to determine which network it belonged to. From there you could contact the network owner to determine which user the IP address was leased to at the time the email was sent. . . although they may require a court order / warrant to give you that information. . . . privacy laws and all that happy stuff.

Dude. He obviously needs it in ENGLISH...

You need to view the raw e-mail and have a look at the headers. The headers are the lines of info that direct the mail. You can see all of the computers that passed it along usually. I can not go into too much more detail without seeing more BUT, ONCE there you will find the first or originating e-mail computer that sent it off and you can take that address and plug it into a network query. You can kinda tell that someone from calguns sent this one off.

Here is what a sample of the headers looks like:

A network query can be found at this link:

Copy and paste the computer and then tell it to DO IT ALL.

Once you see what ISP this generated from you can send them e-mail or make a phone call but their lips will be sealed unless you have a warrant and unless there was a threat made, that is NOT gonna happen. The BEST you can do is try to get them to tell you who that user was but they will likely have a policy against just giving out information. That is what keeps us kinda hidden from a lot of folks out there.

Unless there is something serious nothing can be done except putting the sender into a spam/junk list. Good luck.

[Sleighter]

All of the above is correct, without a court order or really compelling legal reason, an isp won't be telling you who their client is that sent an email. Although it may not be that in depth to answer your question depending on the circumstances.

Does your ex live with her mother? Do they have the same ISP? Why does it even matter if it is your ex or her mom? I can't think of anything that either an ex or her mom could say that I would give 2 hoots about. If they have different ISPs than you can trace it back that far and determine the ISP. Short of that, and hoping that they didn't use a mobile device, good luck.

[xrMike]

is there a way to tell the area they were sent from?

Jeez, with all the grief your ex- has already caused you (based on past threads), and now her mom too?

Sounds like you need to hire a professional at this point, rather than worry about email headers. Maybe you can get a 2-fer discount?

[the86d]

Hell I just started blocking my ex's e-mails and made a separate gmail account for her to yap to, and therefore only check it when I feel like it!

I only check it to see why she is sending child support late, or communication about when my kid is flying to see her...

Or be better than them and just ignore it. It is not hard to block emails.

[lonesniper]

If you have the IP addresses just Google them or download Whois and run them through that. Both should give you information on internet service provider and probably the region of the country they are coming from. It isn't perfect but if the Ex is in one state and Mom is in anoother it should be obvious.

I agree with him.But,You don't need to download anything.
If you have the IP address then you can do Ip search from IP-Details.com .
By doing it you will get information like ISP Name,Location,Country,etc,.
If you need do to whois search Visit WhoisXY.com .It is free web-service ,you don't need to download anything.Just type the Ip address and do whois search.

OP has watched too many procedural cop shows. An IP address has no correlation to any physical address from where it was sent. You can't plug in someone's IP address and find out "aha! she sent this from her mother's house!" The internet doesn't work that way.

*I realize this is an oversimplification but based on OP's follow up questions to posted instructions he clearly thinks he's going to get a street address. That isn't happening.*

[Laythor]

just block the emails. all the info in the header can be spoofed so there is nothing to be gained from it.

so much drama on cal guns.

You actually can get pretty close, or at least tell the approximate provider location if you check the hidden headers:

I used to keep track of someone's location by the IP of e-mail sent to me... of course if they have a HUGE provider that uses like a class C, it might be harder/less-accurate, and I don't think the DHCP scope they drop would be that centralized...

As private individuals, I agree that we do not possess the ability to do so.

However, LEA can and do execute search warrants on ISPs to obtain account holder information based on IP addresses. That is how you correlate IP addresses to physical addresses. How else are RIAA/MPAA filing lawsuits against alleged media pirates? The internet does indeed work that way, but we as private citizens simply do not have access to the tools and legal methods to actually do so.
