IP Addresses
As you probably already know, your IP address is the address or logical location of your computer when it’s connected to the Internet. Networking software/hardware must know your IP address for you to connect and go online. Thankfully, you don’t need to know your IP address every time and enter it in, like a password.…
[Read More]The details of an IP address and all the technology behind it is important mostly to IT guys, the Internet Technology experts who connect computers at your work or who design the networking hardware and software for your computers. Thank goodness they have done such a good job that you never have to think about…
[Read More]What if the U.S. telephone companies suddenly ran out of phone numbers? What kind of panic, if any, would it cause? Though nowhere near as dramatic, that was somewhat the situation facing many North American companies in the summer of 2015…mostly large technical companies that rely on the Internet and networks to survive. But it…
[Read More]Your IPv4 address is a series of numbers and dots, the string of numbers is separated by the dots into four sections, and not all IP addresses have the same number of digits. Your IP address identifies one computer, or one “host,” as they’re referred to on networks. Every device on a TCP/IP network has…
[Read More]When it comes to IP addressing, networking and just about everything else related to computing, it’s important to remember that everything that works behind the scenes is created for computers first, people second. For example, an IP address, which points to a designated computer or even a website, is designed to help computers—not computer users—…
[Read More]We figured that most visitors to WhatIsMyIPAddress.com don’t know a lot about IP topics — and why would they? For the most part, only people involved in IT (information technology) and computer networking need to think about what the IP in IP address stands for. Still, sometimes the terminology and jargon used (and rarely explained)…
[Read More]IP Addresses and Datagrams The IP protocol, which is one of several TCP/IP protocols, provides a hierarchal, hardware-independent addressing system—in other words, it’s the built-in networking software on computers that is needed for delivering data on a complex, routed network like the Internet. Although it’s the network adapter on a computer that has a unique…
[Read More]The “IP” part of IP address stands for “Internet Protocol.” The “address” part refers to a unique number that gets linked to all online activity you do…somewhat like a return address on a letter you’d send out. (All this happens in milliseconds.) That’s the end of today’s lesson. At least it should be. Because from…
[Read More]Here are the cold hard facts: An IP address is a 32-bit binary address. This 32-bit address is subdivided into four 8-bit segments called octets. Since only a fraction of people work with 32-bit binary addresses or even 8-bit binary octets (math and computer types), the IP address is almost always expressed in what’s called…
[Read More]We don’t “own” our IP address—for instance, it’s not like a homeowner’s address, which is linked to a piece of land and a building on it. Your IP address can change and it’s never really tied to your name or address, at least not in a way the public can see it. But this doesn’t…
[Read More]How Your IP Address Could Lead Anyone to Your Front Door You probably don’t think too much about your IP address, but maybe it’s time you did. Most people (and maybe you) know their IP address is a digital address of some sort that helps the Internet deliver content to your computer. And perhaps you…
[Read More]A hacker is simply an online vandal, if you think about it. What do vandals do but damage things that don’t belong to them, for no good reason other than to do it. A hacker wants to worm his way into a network of his choosing to do serious (or not-so-serious) damage, such as stealing…
[Read More]Do you know anyone who doesn’t use email? It’s not likely. Email is as common as having a telephone for just about all of us. There are about two billion email users around the world. In 2012, Google said it had 425 million email users worldwide, and Microsoft said it had more than 360 million…
[Read More]When you sign up with an Internet Service Provider (ISP), you will either end up with a static IP address or a dynamic IP address. What’s the difference between the two? Haven’t you ever marveled at how the internet knows how to get information directly to your computer? It’s not magic: your IP address is…
[Read More]Every time you visit a website, you are interacting with the largest distributed database in the world. This massive database is collectively known as the DNS, or the Domain Name System. Without it, the Internet as we know it would be unable to function. The work that the DNS does happens so seamlessly and instantaneously…
[Read More]Classless inter-domain routing (CIDR) is a set of Internet Protocol (IP) standards that is used to create unique identifiers for networks and individual devices. The IP addresses allow particular information packets to be sent to specific computers. Shortly after the introduction of CIDR, technicians found it difficult to track and label IP addresses, so a…
[Read More](Go to our Blacklist Check page to find out if your IP address is listed on an anti-spam database. This article explains why that happens and how to get off a blacklist.) Each blacklist database has its own criteria for flagging IP addresses and compiling its own list of online offenders. Those criteria could include…
[Read More]A VPN (Virtual Private Network) lets you get around the walls that websites, networks and countries put up to deny you access to content you have a right to see. Once you connect to your VPN, a website can no longer see or “know” your actual IP address: They see an IP address that’s not on a “block” list, because it’s one provided by your VPN.
[Read More]You’ve probably heard of an IP address and understand that it has something to do with your Internet. However, if you don’t fully grasp what IP means, don’t worry – you’re not alone. We will guide you through the IP basics. Although your IP address provides the passport to all things Internet-related, there aren’t many instances where…
[Read More]You see it all of the time in spy thrillers and police dramas. From The Bourne Supremacy to Criminal Minds, we see a suspect traced to their exact, hidden location using IP geolocation, and based on its accuracy, the good guys burst in to save the world from peril. No matter what technological tricks the…
