How IP address is structured

Most of you must have tried to understand how IP address works and how it is built with a series of numbers separated by dots. (xx.xx.xx.xx)

There is so much behind this configuration & this may surprise you there is a big logic behind these series of numbers & all the Internet works only on this number series called as IP address.


Every station on a PSN (packet switched network) that is based on the TCP/IP protocol (your computer is one, for example. Yes, we're referring to a host that is connected to the net) must have an IP address, so it can be identified over the network, and information can be relayed and routed to it in an orderly fashion.

An IP address consists of a 32 bit logical address. The address is divided into two fields:

1. The Network Address

Assigned by Inter-NIC (Internet Network Information Center). In fact most ISP's (internet service providers) purchase a number of addresses and assign them to individuals.

2. The Host Address

An address that identifies the single nodes throughout the network. It can be assigned by the network manager, by using protocols for it such as DHCP, or the workstation itself.

[The IP networking protocol is a logically routed protocol, meaning that address (it could be any random IP address) will be on the same physical wire as address (of course this is not always true. It depends on the subnet mask of the network, but all of that can fill a text of its own)

IP address structure

   ^             ^
   |              |
network   host

Every " --- " = 8 bits.
The first bits ===> network address
The last bits  ===> host address.
with 8 bits you can present from 0-255 . (binary=(2 to the power of 8)-1)

11000010.01011010.00011111.01001010 (binary) (decimal)
IP address CLASSES :
We can classify IP addresses to 5 groups. You can distinguish them by comparing the "High Order" bits (the first four bits on the
left of the address):


Notice the address range 127.X.X.X.
These addresses are assigned to internal use to the network device, and are used as an application tool only. For example:, the most common one, is called the loopback address - everything sent here goes directly back to you, without even traveling out on the wire.

Also, some IPs are reserved for VPNs - Virtual Private Networks. These are local area networks over wide area networks that use the Internet Protocol to communicate, and each computer inside the network is assigned with an IP address. So, suppose a certain computer wants to send a data packet to another host on the network with the IP 'x', but there's also another host on the Internet that has the same IP - what happens now? So this is why you cannot use these and other forms of reserved IPs on the Internet.


Distinguishing different groups:

You have to compare the first byte on the left in the address as follows:


Yes, we know, we've left A LOT of things unexplained in this text. With time, I will write more tutorials to cover these and other subjects.

weird shit (newbie note):


(copied from RFC 1112)
IP multicasting is the transmission of an IP datagram to a "host group", a set of zero or more hosts identified by a single IP destination address. A multicast datagram is delivered to all members of its destination host group with the same "best-efforts" reliability as regular unicast IP datagrams, i.e., the datagram is not guaranteed to arrive intact at all members of the destination group or in the same order relative to other datagrams.

The membership of a host group is dynamic; that is, hosts may join and leave groups at any time.  There is no restriction on the location or number of members in a host group.  A host may be a member of more than one group at a time.  A host need not be a member of a group to send datagrams to it.

A host group may be permanent or transient.  A permanent group has a well-known, administratively assigned IP address.  It is the address, not the membership of the group, that is permanent; at any time a permanent group may have any number of members, even zero.  Those IP multicast addresses that are not reserved for permanent groups are available for dynamic assignment to transient groups which exist only as long as they have members.

Internetwork forwarding of IP multicast datagrams(ip packets)is handled by "multicast routers" which may be co-resident with, or separate from, internet gateways.  A host transmits an IP multicast datagram as a local network multicast which reaches all immediately-neighboring members of the destination host group.  If the datagram has an IP time-to-live greater than 1, the multicast router(s) attached to the local network take responsibility for forwarding it towards all other networks that have members of the destination group.  On those other member networks that are reachable within the IP time-to-live, an attached multicast router completes delivery by transmitting the datagram(ip packet) as a local multicast.

*if you don't understand the above do not worry, it is complicated and dry but reread it and read it again get a dictionary if it helps. Hacking is not easy.


Most Significent Bit

In set numbers the first number on the left is the most important because it holds the highest value as opposed to the LSB=> least significent bit, it always holds the the smallest value.

That;s it for now guys, I will be writing more articles to unleash more secrets & knowledge that somehow will help you for sure. For any doubts that you might have you always have a comment section right below, feel free to comment your query or any feedback. It will really be appreciated.

Step by step guide to block a website

Hey Folks,

Ever tried to block a website, No?

There are several reasons why you might want to block a certain websites on your computer/laptop. It may be because of some virus transmitting websites, or to secure your personal data or to avoid it from your kids or many more reasons.

Well there are many ways to block any website that you wish to block, it may be using some external software, browser settings or the most efficient way is to add an entry in windows hosts file.

Site blocking

1. Blocking at OS level:

- DNS system works as a backbone of Internet, & DNS system translates IP addresses to easy to remember names (for example You can't remember IP addresses of all the web sites, so DNS system gives you privileges to give your IP address a name that you can remember easily.

See my article to know more on DNS & how it works: Click Here

Visit the link to get IP address: How to find IP address from URL

On Operating System level, we have a hosts file that keeps this information handy. And you can put the websites in this file that you want to block.

a. You must have administrator privileges to access this file.

b. This file is located in your "C" drive:


c. Open the file in Notepad. (Double click the file, select Notepad from the list of applications)

d. At the end of this file, you can make an entry of the website that you no longer wish to visit anymore.

e. Entry should be like:

IP Address         <website URL>
IP Address         <website URL>
IP Address         <website URL>
IP Address         <website URL>

and so on.... You can make as many entries as you want.

f. For example, if you wish to block, then add the details accordingly: 
"127.00.1". (without quotes)

You can make one entry per line.

g. Add all the websites that you wish to block, & save this file now.
h. Reboot the system for this file to take effect, & you are done. The websites are blocked as per your wish.

2. Blocking at Browser level:

There are many browsers available, but the most popular ones are "Google Chrome" & "Mozilla Firefox". Both these browsers gives many add-ons that can serve your purpose. One of the popular add-on is BlockSite, this is available for both the browsers.

a. Once you have installed the extension in your browser, go to extensions page (inside settings, extensions at left side bar)

b. Go to its options, & add the site name that you wish to block in the text bar provided.

c. Save the settings, & that it. The site is blocked now.

DNS - Domain Name System

DNS - Domain Name System

Guys, how about the world with only IP addresses? Ever wondered if you have to open but instead of this simple URL, you have to type in its IP address every time? In fact for all the web-sites you use, you have to use its IP address to open it up. How the life would be? So just give it a thought.

This is the importance of DNS (Domain name system).

What is DNS

Domain Name System is undoubtedly a central part of Internet, providing a way to resolve a series of numbers to a name. Every device say mobiles, laptops, tablets, phablets, computers, watch connected to internet has got its own unique series of numbers called as IP address that locates the device over the internet. For example you laptop has got an IP address (click to find your IP address), obviously it is very hard to remember. Also if you think of remembering one IP address, there are hell lot of IP addresses you go to everyday. How many will you remember? Here is when DNS comes into picture. You are typing in your browser, but in backend it is calling its IP address that you don't even know & the page will be opened ready for you to access. This is what DNS does in your daily life.

How DNS works

DNS is based on client server architecture. DNS client (any internet user) send requests to and receive responses from DNS servers. Requests called containing a name, that result in IP address being returned from the server, are called forward DNS lookups. On the other hand Requests containing IP addresses and resulting in a name are called as reverse DNS lookup. DNS functions on a distributed database to keep these names and last known address information for all public hosts over the internet.

When client like web browsers issue requests involving internet host names, it first contacts the DNS server to find its IP address, if the current server doesn't have the IP address it will automatically forward it to next DNS server. After several forwardings the IP address for the given host eventually resolves & come back with an opened page on the clients side.

How to modify exe files

Guys, today I am gonna show you how you can modify exe files. 

Note: Do this if you are highly confident on what you are doing, else you will end up corrupting your exe file.

How to modify exe files

Learn how to change *.exe files, in 5 easy steps:

1. Don't try to modify a prog by editing his source in a dis-assembler. Why?
Cause that's for programmers and assembly experts only.

Try to view it in hex you'll only get tons of crap you don't understand.
First off all, you need Resource Hacker. 

It's a resource editor and very easy to use.
You can download it at

2) Unzip the archive, and run ResHacker.exe. You can check out the help file too.

3) You will see that the interface is simple and clean. Go to the menu FileOpen or press Ctrl+O to open a file. Browse your way to the file you would like to edit. You can edit *.exe, *.dll, *.ocx, *.scr and *.cpl files, but this tutorial is to teach you how to edit *.exe files, so open one.

4) In the left side of the screen a list of sections will appear.
The most common sections are
-String table;
-Cursor group;
*Icon: You can wiew and change the icon(s) of the program by double-clicking the icon section,chossing the icon, right-clicking on it an pressing "replace resource". After that you can choose the icon you want to replace the original with.
*String table: a bunch of crap, useful sometimes, basic programming knowladge needed.
*RCData: Here the real hacking begins. Modify window titles, buttons, text, and lots more!
*Dialog:Here you can modify the messages or dialogs that appear in a program. Don't forget to press "Compile" when you're done!
*Cursor group: Change the mouse cursors used in the program just like you would change the icon.
*Bitmap: View or change images in the programs easy!
*WAV:Change the sounds in the prog. with your own.

5) In the RCData,Dialog,Menu and String table sections you can do a lot of changes. You can modify or translate the text change links, change buttons, etc.

TIP: To change a window title, search for something like: CAPTION "edit this".

TIP: After all operations press the "Compile Script" button, and when you're done editing save, your work @ FileSave(Save as).

TIP: When you save a file,the original file will be backed up by default and renamed to Name_original and the saved file will have the normal name of the changed prog.

TIP: Sometimes you may get a message like: "This program has a non-standard resource layout... it has probably been compressed with an .EXE compressor." That means that Resource Hacker can't modify it because of it's structure.

This is how you can modify your exe files and make them work as you want. So you guys have this article now and you have your exe files, why not play around with them. ;)

How to delete an undeletable file

Delete An "undeletable" File

1. Open a Command Prompt window and leave it open.
2. Close all open programs.
3. Click Start, Run and enter TASKMGR.EXE
4. Go to the Processes tab and End Process on Explorer.exe.
5. Leave Task Manager open.
6. Go back to the Command Prompt window and change to the directory the AVI (or other undeletable file) is located in.
7. At the command prompt type DEL <filename> where <filename> is the file you wish to delete.
8. Go back to Task Manager, click File, New Task and enter EXPLORER.EXE to restart the GUI shell.
Close Task Manager.

Or you can try this

Open Notepad.exe

Click File>Save As..>

locate the folder where ur undeletable file is

Choose 'All files' from the file type box

click once on the file u wanna delete so its name appears in the 'filename' box

put a " at the start and end of the filename
(the filename should have the extension of the undeletable file so it will overwrite it)

click save,

It should ask u to overwrite the existing file, choose yes and u can delete it as normal

Here's a manual way of doing it. I'll take this off once you put into your first post zain.

1. Start
2. Run
3. Type: command
4. To move into a directory type: cd c:\*** (The stars stand for your folder)
5. If you cannot access the folder because it has spaces for example Program Files or Kazaa Lite folder you have to do the following. instead of typing in the full folder name only take the first 6 letters then put a ~ and then 1 without spaces. Example: cd c:\progra~1\kazaal~1
6. Once your in the folder the non-deletable file it in type in dir - a list will come up with everything inside.
7. Now to delete the file type in del ***.bmp, txt, jpg, avi, etc... And if the file name has spaces you would use the special 1st 6 letters followed by a ~ and a 1 rule. Example: if your file name was bad file.bmp you would type once in the specific folder thorugh command, del badfil~1.bmp and your file should be gone. Make sure to type in the correct extension.
