An Introductory Road Map to IP Addresses

When you get a letter in the mail, how do you know it was intended for you? The answer, of course, is because it is addressed to you. Computers have addresses as well, known as Internet Protocol addresses or simply IP addresses. Knowing how to use an IP address is a key component to being able to effectively navigate the Internet. By managing your own IP, you can determine who has access to your machine and much more.


The TCP/IP Protocol

The heart of a computer’s ability to navigate the Internet and receive information is the Transmission Control Protocol, or TCP. The TCP/IP protocol forms the standard of all online communication. TCP is used to connect to servers on the Internet and is essential to being able to send data. Meanwhile, IP serves as the unique identifier for your individual computer and is essential to being able to receive information fr om other sources. Your IP address comes in one of two different forms: IP Version 4, or IPv4, and IP Version 6, or IPv6. All computers have at least an IPv4 address, and many computers are now using an IPv6 address as well. The difference between them boils down to a matter of complexity.

Exploring the Basics of DNS

What’s in a name? In the case of DNS, the answer is quite a bit. DNS, or Domain Naming System, is one of the basic building blocks of the online world. This naming system allows a computer to be identified by other machines, which is essential to web based communications. Most systems automatically set a DNS, but there are advantages to knowing more about it and being able to customize the system for your own purposes. Read on to find out more.


The Phone Book of the Internet

Many people refer to DNS as the phone book of the Internet, because that is essentially what it is. If a site’s public IP address serves as its phone number, its DNS name is the actual phonebook listing. To clarify, every website out there has a public IP address. This is usually represented by four sets of numbers separated by dots, such as 208.102.31.80. In fact, if you type in “http://” followed by the IP address into your browser’s navigation bar, you will land at that site just as though you had entered its domain name. However, most people remember names better than numbers, so it’s easier and more effective for a company to use a memorable domain name rather than the public IP address.

Wake on LAN Network Options: A Great Remote Solution

What do you do when you need to turn on a computer at a remote site that’s been shut down? You could call somebody on site, but that only works if they’re actually there. If you need access to a computer on off hours, during the weekend, or in another situation where having somebody turn it on for you is inconvenient or impossible, there is a simple solution. This solution is called Wake on LAN, and it is an effective way to improve your remote access abilities.


What is Wake on LAN?

If you have a Wake on LAN adapter on your network router, that means that you can remotely turn on any computer that you have set to work with the adapter. The network reads an incoming ping from a remote computer and then executes a command to start the sel ected computer. This turns on the computer but doesn’t execute any other operations. When doing work on a network or making software upgrades, you will usually only need to have the remote computer turned on in order to perform whatever tasks you have scheduled. If you have something more complex in mind, you might need to log in to the newly awakened computer remotely in order to perform the tasks you need to do.

5 Tips that will Boost your Network Security

How good is your network security? Many people assume that it’s fine because they haven’t had to deal with viruses or malicious attacks, but you might be more unprotected than you think. If you use remote utilities and require a functional network at all times, you should take the steps outlined below to protect yourself. Not only will this keep you safe from viruses, but it will also protect against other malicious attacks that might slow your network down.


1: Configure and Protect your Firewall

Having a good firewall is a must for any business, but you need to make sure that you configure it properly. Make sure that you test any and all software that will be used remotely via a remote gateway before you put it into practice. You should make sure to close off all ports that don’t need to be open in your firewall, but you also don’t want to accidentally block anybody who is legitimately using remote access. You should also make sure to password protect your firewall. Many people make the mistake of assuming that a firewall can’t be breached, but if you don’t add security to who can access it, you might find your first line of defense in network security taken over by hackers.

2: Keep your Firmware Updated

Typical routers used by small businesses usually go out of date within a year. Because of this, it’s a good idea to check for firmware updates to your router and firewall at least once a year, and preferably once every six months. You can check for updates by opening the router admin screen. Many products come with an even easier option to check for updates, which can be put right on your network administrator’s desktop. Each time you update the firmware, you should also make sure to check out the manufacturer’s website. Most router and firewall suppliers have a news section that can keep you up to date on all the latest developments and whether any security issues have been raised lately.

The Past, Present, and Future of Wi-Fi

If you’re like most people, who have at least one device that uses Wi-Fi to connect to the Internet. We’re well past the days when getting online meant using a phone cable and hearing the screeching sound of a modem whenever you got started. Nowadays, people use Wi-Fi for everything fr om casual Internet use to business networking. Where has Wi-Fi been and wh ere will it be going in the future? This article will explore its past and present as well as things still to come.


A History of Wi-Fi

Wi-Fi was born in 1985 when the Federal Communications Commission (FCC) designated a specific radio frequency for industrial, scientific, and medical use. This frequency was later used by AT&T for cashier systems, allowing stores to tap into their databases through the radio frequency without having to have an actual connection. In Australia, a scientific research project designed to detect exploding mini black holes ended in failure, but the byproduct was a breakthrough in Wi-Fi technology. The Commonwealth Scientific and Industrial Research Organization (CISRO) obtained patents to clear up garbled radio signals from the experiment, and a broader online application was discovered in the process.

A Complete Overview of Network Address Translation

Did you know that there is a way to convert your entire network to only one IP address? This method is known as network address translation, or NAT. That is only one use of the technology, however. It can also increase security and provide a smoother overall browsing experience depending on how it is used. This article will discuss the history of NAT and both the advantages and drawbacks of using it for your business network.


The History of NAT

NAT originated as a result of how the Internet in general and IPs specifically work. Any computer that accesses the Internet needs to have an IP address in order to do so. Because IP addresses have a limited number of digits, there are only so many of those addresses to go around. While this wasn't an issue in the early days of the Internet, it became an issue later on. As a workaround for this problem, NATs were born. Using an NAT means that your entire network has one IP address, through which many different computers can access the Internet. This limits the number of existing IP addresses that get used and can also have several security benefits when implemented properly.
