How can we track the IP address to the right person?

I'm getting text messages and emails from someone who is using a gmail and yahoo account. I think they may be using someone's wireless internet connection to send the text messages. If they are using a friend's or public internet connection then how can you track the ip address?

2. no..the only way u can track a IP address is if u run a website..
3. Lots of software that can do a lot of this what you seek: CallerIP Visual IP Trace VisualRoute (there lite version for freeware also) Path Analyzer Pro These use a map of the world and visual effect shows you where on the globe where the person is located and IP and domain use so you can file a complaint.
4. if you are getting this e-mails on yahoo you can view the external IP address of the originator's computer just go to: Open the e-mail On the main body of the email on the right hand side click on compact head it then gives the option to click full header this is going to give you a long list of numbers and letters.

Once there type IPCONFIG -a 76.222.252.60 Press ENTER this will give you some thing like this: C:\>ping -a 76.222.252.60 Pinging adsl-76-222-252-60.dsl.frs2ca.sbcglobal.net [76.222.252.60] with 32 byte s of data: Reply from 76.222.252.60: bytes=32 time=38ms TTL=51 Reply from 76.222.252.60: bytes=32 time=88ms TTL=51 Reply from 76.222.252.60: bytes=32 time=41ms TTL=51 Reply from 76.222.252.60: bytes=32 time=38ms TTL=51 Ping statistics for 76.222.252.60: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 38ms, Maximum = 88ms, Average = 51ms where the full IP is: adsl-76-222-252-60.dsl.frs2ca.sbcglobal.net this indicates that this person's internet service provider is SBC Global all internet company's have a "Service Abuse" department for example AT&T's http://helpme.att.net/servabuse.php you can contact this internet service provider and let them know the circumstance (they will normally call you back within 24hrs) they can notify the owner of this network (wired or wireless) who should be able to check his router logs and find out the IP and MAC address of the “intruder” than use a sniffer software such as DONTSTEALMYWIFI to view the internet activity of this person. you can also get the USER ID date and exact time of this message (and if you can get the server name wher this come from this by doing netstat -n) and report to yahoo or whom ever the IM provider is here is a link to yahoo's service abuse: http://help.yahoo.com/help/uk/mesg/abuse/index.html I HOPE THIS HELPS I KNOW IS LONG BUT I’M TRYING TO INCLUDE EVERY THING I KNOW TO HELP YOU AS MUCH AS I CAN. PLEASE CONTACT ME IF YOU NEED ANY MORE HELP. ********YET ONE MORE THING: If this person is using yahoo messenger it realy realy hard to trace his or her IP due to the fact that messenger sends messenges to a server who in turn sends this message to a database server (with a list of users) who sends the message to you and backwards this means that if you run netstat -n you will get an IP but it will be the IP of the Instant message service provider like yahoo for example: cs20.msg.dcn.yahoo.com:5050 ESTABLISHED I hope this helps and have a HAPPY NEW YEAR!
