Secret Behind Your Network n Broadband IP.....???Every 1 Shud Kno..



Secret Behind Your Network n Broadband IP.....???Every 1 Shud Kno..

The IP address shown on the website on the Internet is different from ur real IP address .This is due to Port Address Translation (PAT) and Network Address Translation (NAT)



The concept is simple..
I will explain you..

You have an IP address (real IP provided by your network.Let us call it Private IP address) and you use it to send a request packet to view a website.webpage.


Now I will tell you how the packet travels..

The packet goes to your gateway/router using the Private IP address..Then from there it changes its Ip and converts to an IP..lets say it Public IP address.Now if you access Internet,there,your Public IP will be shown and not Private IP address(For security reasons..ofcourse)



Now if you check ur Ip on www.tracemyip.com..then also it shows ur public IP address,for example: 122.xxx.xxx.xxx but ur actual IP would be some 172.xxx.xxx.xx, or something like that..



Hope you understood this concept.PAT actually means,assigning one particular Public IP to whole of a network.This service was started to save IP addresses,coz there are only 4.3 billion IPs in all.

By doing this the IP addresses are saved..if not using NAT,one public IP would have to be provided to every one Private IP..which would result in an unwanted loss of IPs...



i hope all would kno from tis..

Entering LAN After Obtaining IP






After getting the ip address  Of d Sytem ,and detecting which ports are open
how to enter into victim system


The first thing you needed to specify is whether the IP address obtained by you is in your LAN?
 


If its in your LAN,then follow these steps:

1) Run cmd(commandprompt)

2) Type nbtstat -A

For example,if you have found the IP address 123.23.13.22 available and with open ports,then type:
nbtstat -A 123.23.13.22
If you get the hex code <20> beside the name of the victim's computer, then it means that the victim's computer has sharing enabled(Its a good sign!)

3) Now if you get that hex code <20> then type:

net use z: \\123.23.13.22\SharedDocs


It shows 'The command completed successfully'

4) Now open My computer,there you will find the drive Z,open it,its the shared documents folder of the victim.

5) Now if you want to access the drives of that system,then run cmd,then type:
net use y: \\123.23.13.22\C$ "" /u:""

Now it will prompt for you to give the username and password of that system...The username will be shown on the drive Z as 'SharedDocs on xxxxxx(123.23.13.22)'


6) Try guessing the password or Bruteforce it. After getting the password,type it and you will get the access to your target computer.

7) If the message 'Access is denied' appears,then it means you have to evade his firewall..,use Firekill Firewall Killer2000

8)After doing this,repeat the step 5 and give the username and password and it will surely show ' The command completed successfully.'

9) Thats it...you will be in the root of the victim's com.


(Plz note: Do this act only to prevent hacking,not to implement it.)
