IP Address, Mac addressing, Packet and Protocols

What is an IP Address?

An IP address is something that allows one computer to communicate with another via the internet. In the same sense that someone needs your mailing address to send you a letter, a remote computer needs your IP address to communicate with your computer.

What does it consist of?

An IP address consists of four numbers, each of which contains one to three digits, with a single dot (.) separating each number or set of digits. Each of the four numbers can range from 0 to 255. Here's an example of what an IP address might look like:

Pros, Cons and examples of an IP address


Less downtime – Each time your IP address refreshes you run the risk of downtime from the server. While this is usually only for a very short time, it can wreak havoc on your gaming. Having a static address eliminates this risk.

If you have your own IP (not a shared one), you could not be hurt by your IP "colleagues":
- you will not be in the situation when your IP "colleague" send email spam, and you will be also will be catalogued as spammer.


Open Proxy Browser-Open proxies are also known for being sources of spam, and may put your IP address at risk for being spied on, which kind of defeats the purpose of changing it in the first place.

What is MAC Addressing?

Short for Media Access Control address, a hardware address that uniquely identifies each node of a network.(Node in networks, a processing location. A node can be a computer or some other device, such as a printer. )

What's the purpose of MAC Addressing?

The purpose of MAC addresses is to provide a unique hardware address or physical address for every node on a local area network (LAN) or other network. A node is a point at which a computer or other device (e.g., a printer or router) is connected to the network.


Everything you do on the Internet involves packets. For example, every Web page that you receive comes as a series of packets, and every e-mail you send leaves as a series of packets. Networks that ship data around in small packets are called packet switched networks.

On the Internet, the network breaks an e-mail message into parts of a certain size in bytes. These are the packets. Each packet carries the information that will help it get to its destination -- the sender's IP Address, the intended receiver's IP address.

Protocol ( very simple)

In computing, a protocol is the language used by computers while talking with each other. In its simplest form, a protocol is the rules used in talking and communication between computers.
