CBC Encryption

Wed Mar 25, 2015 6:41 pm by ORLP2

For those who don't know me, I am ORLP (lowercase or upper-case will do, I honestly aren't fussed). I am a Computer Science and cryptography enthusiast. I am looking to broaden my horizon within the "computer security" scene, even if that means joining a newly-crafted forum to get my name across and meet other people who have similar interests as me.

I would like to start by saying I'm …

Introduction to IpV4

Post  Orianthi on Fri Mar 20, 2015 7:29 pm

[b]Introduction: [/b]IpV4 is the fourth version in the development of the Internet Protocol (IP) Internet, and routes most traffic on the Internet. The common syntax of IPv4 is X.X.X.X. Each octet is 0 - 255. A couple examples are below:

192.168.1.1 //Private IP Address
32.122.89.5 //Public IP Address
127.0.0.1 // Localhost
255.255.255.255 //Broadcast

A private IP address is an address that [b]ONLY[/b] people in your LAN(Local Area Network) can see. This is viewable with the following commands:
[code]
Windows[open cmd]-- ipconfig
Linux/Mac[open terminal] -- ifconfig
[/code]

A public IP is an address that allows anyone to view. People within the internet can view this IP address, and you want to protect this IP address as it can define who you're and where you are from within the internet. Think of this address as your house on the Internet. 

Localhost is an address that allows you to access your own computer within the network. Don't worry [b]only[/b] the computer that does 127.0.0.1 can access it.

Broadcast addressing is where we send packets out to everyone on the network. WAL packets(Wake on Lan) are typically sent over broadcast.
