Question : when I type the command in Dos "Netstat" I will see all the connections to my PC/Internet.But if I see only the host number , how can I find out to whom that number belongs?? Traceroute?? Here is an example of my recent Netstat : Active Connections Proto Local Address Foreign Address State TCP localhost:3008 ESTABLISHED TCP localhost:44334 ESTABLISHED TCP localhost:1032 ESTABLISHED TCP localhost:1030 ESTABLISHED TCP localhost:44334 ESTABLISHED TCP localhost:3009 ESTABLISHED TCP localhost:1024 ESTABLISHED TCP localhost:3006 ESTABLISHED TCP localhost:1027 TIME_WAIT TCP localhost:1027 TIME_WAIT TCP localhost:1028 ESTABLISHED TCP localhost:3004 ESTABLISHED TCP supportcenter.verizon.net:http CLOSE_WAIT TCP go.microsoft.com:http TIME_WAIT TCP go.microsoft.com:http TIME_WAIT TCP www.infospace.com:http ESTABLISHED TCP es.verizon.net:http ESTABLISHED TCP 130.81.64.18:http ESTABLISHED TCP 130.81.64.18:http ESTABLISHED TCP guides.infospace.com:http ESTABLISHED TCP dcshelp.verizon.net:http ESTABLISHED TCP uvox1-chi-slot3l.stream.aol.com:http TIME_WAIT TCP uvox1-chi-slot3l.stream.aol.com:http ESTABLI

Get TcpView from SysInternals (free) ▫ TcpView (SysInternals) It will show you real-time info about the connections that your computer is making, and it has a DNS name-resolver that will turn those IPs into readable DomainNames. If you want to find out to whom an IP belongs, then check it at the IANA database for the region that the IP comes from: http://www.iana.org/ipaddress/ip-addresses.htm For example, if the DomainName ends with .be (=Belgium), then click the link to the RIPE database and enter the IP in their searchbox. Sometimes, you'll have to guess what region the IP/DomainName is from. ___________________________________________ ☺ [Belgium, GMT+1]_________________________svg

Thanks for u reply, what about the localhost numbers?? those are not IP adresses, how can i locate or track those numbers ??

localhost is a placeholder for the name of the computer on which a program is running; localhost uses the reserved loopback IP address 127.0.0.1. i_XpUser

Thanks for the great resource (TCP View) will use it !!
