Everything about IP and PORTS

What is an IP address

Everyone connected to the Internet has an IP or Internet Protocol address. It's a set of numbers separated by dots. Something like 192.168.1.1 and is the Internet equivalent of a phone number.

Each segment of the IP number can have a value as high as 255 and as low as 0.

Essentially an IP address is a unique identifier that is used to route information from the Internet to the requesting machine.

Your computer's IP address will never be the same as someone else. There is one exception to this rule. If your computer is on a network behind a corporate firewall - that's a computer between a network and the Internet - then you could have an IP address unique to your network, but not to all networks.

Getting ip.

mIrC U can use an irc client ex. mirc and u can /dns nickname. ( ex. if the nick is AM2o type /dns AM2o ). Take a look in the status window and the ip is there.

ICQ Open a trojan ex. Sub7 and click on the IP button type on the line that says "ICQUIN" type the victims ICQ number, then press "resolve UIN" and it will give you there IP number, go back to the main screen and put in the IP on the "IP/UIN box" now in the box next to that put in the port you set the server to [27374 is the default] now click connect and your should be in!

Netstat When u are receiving/sending a file or a programm from/to someone, u making a thing called "Direct Transfer". Open ur msdos (goto start button -> run -> command) and type in netstat. This will show u the ip or host of the user who is receiving/sending from/to a file or programm. This can be used as well as if u are chatting with someone (ex. ICQ chat). Just msg the user, do a netstat -n and the ip will be shown. If a host is shown, just ping the host and get the ip.

C:\Documents and Settings\AM2o>netstat

Active Connections

Proto Local Address Foreign Address State
TCP AM2o-nk255s:2345 adsl-255-236.***:4906 ESTABLISHED <----- This is the host of person connected on ur PC
TCP AM2o-nk254s:2346 crl.***.com:http CLOSE_WAIT <----- Other connection, not interested to it


C:\Documents and Settings\AM2o>ping adsl-255-236.***

Pinging adsl-255-236.*** [215.34.123.***] with 32 bytes of data:

Ping statistics for 215.34.123.***: <----- This is the ip we want
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

C:\Documents and Settings\AM2o>

Ipconfig Open ur msdos (goto start button -> run -> command) and type in ipconfig. This will show you ur ip address.

NOTE: Netstat can be used with ICQ, mIrC, AOL etc.

NOTE: If a user is connected on a proxy or wingate (hidding his real ip) u cant know his real ip.

Behind an adsl.

REAL IP address ---> ADSL IP ---> INTERNET

This is show as simple as possible what happens when you have adsl. Your real ip its hidden with a fake one (the one set by adsl). An attacker needs the real ip address to connect on a remote user. Visit www.showmyip.com or download IPHunter from Trojans section.

Using netstat.

NETSTAT [-a] [-e] [-n] [-s] [-p proto] [-r] [interval]

  • -a Displays all connections and listening ports.

  • -e Displays Ethernet statistics. This may be combined with the -s
    option.

  • -n Displays addresses and port numbers in numerical form.

  • -p proto Shows connections for the protocol specified by proto; proto
    may be TCP or UDP. If used with the -s option to display
    per-protocol statistics, proto may be TCP, UDP, or IP.

  • -r Displays the routing table.

  • -s Displays per-protocol statistics. By default, statistics are
    shown for TCP, UDP and IP; the -p option may be used to specify
    a subset of the default.

  • interval Redisplays selected statistics, pausing interval seconds
    between each display. Press CTRL+C to stop redisplaying
    statistics. If omitted, netstat will print the current
    configuration information once.

Finding ports.

Port Scanner You can Download a program called Port Scanner (available in our site in "scanners" section).

Netstat Once again you can use the netstat.
