If you already know the concept, feel free to skip to the next chapter.Īs soon as we are on the Internet with a device, we receive a so-called IP address. He loves long walks on virtual beaches, playing worker placement board games with inconsequential themes, and spending time with his family and menagerie of pets and plants.Before we can go deeper into the topic of localhost and its applications, it makes sense to understand how our computer normally communicates with the Internet and how IP addresses work. If you're looking for him after hours, he's probably four search queries and twenty obscenities deep in a DIY project or entranced by the limitless exploration possibilities of some open-world game or another. While his days of steering students toward greatness are behind him, his lifelong desire to delight, entertain, and inform lives on in his work at How-To Geek.

In addition to the long run as a tech writer and editor, Jason spent over a decade as a college instructor doing his best to teach a generation of English students that there's more to success than putting your pants on one leg at a time and writing five-paragraph essays. In 2023, he assumed the role of Editor-in-Chief. In 2022, he returned to How-To Geek to focus on one of his biggest tech passions: smart home and home automation. In 2019, he stepped back from his role at Review Geek to focus all his energy on LifeSavvy. With years of awesome fun, writing, and hardware-modding antics at How-To Geek under his belt, Jason helped launch How-To Geek's sister site Review Geek in 2017. After cutting his teeth on tech writing at Lifehacker and working his way up, he left as Weekend Editor and transferred over to How-To Geek in 2010. He's been in love with technology since his earliest memories of writing simple computer programs with his grandfather, but his tech writing career took shape back in 2007 when he joined the Lifehacker team as their very first intern. Jason has over a decade of experience in publishing and has penned thousands of articles during his time at LifeSavvy, Review Geek, How-To Geek, and Lifehacker. Prior to that, he was the Founding Editor of Review Geek. Prior to his current role, Jason spent several years as Editor-in-Chief of LifeSavvy, How-To Geek's sister site focused on tips, tricks, and advice on everything from kitchen gadgets to home improvement. He oversees the day-to-day operations of the site to ensure readers have the most up-to-date information on everything from operating systems to gadgets. Jason Fitzpatrick is the Editor-in-Chief of How-To Geek. The difference shown here is that there exists two routes - a general route to any device using 127.x.y.z and a very specific route to host 127.0.0.1 (which is in 127.0.0.0), both of which use the 127.0.0.1 interface So to answer the original question, no you can't use 127.0.0.0 and 127.0.0.1 interchangeably. The third column specifies where traffic should go next to get to the destination (if you are going to Canada, you need to start by getting on Main Street) and the fourth column indicates which path out of the device should be used to get to the destination (from home you may only have your driveway but from the Walmart parking lot you may have several 'exits' to choose from).įinally, the metric gives the computer a way to choose the best path if there are multiple routes to the destination (you can go out either the north or east exit from the parking lot to get to Canada, but the east one is a faster). So a value of 0.0.0.0 covers going to any device and a value of 255.255.255.255 specifies an individual device. Without getting into great detail, the 'higher' the mask value, the more specific the destination.

The first column provides the list of known destinations (where can I go) and the second column indicates how specific the destination (I can go to Canada or I can go to Uncle John's house in Canada).

In some ways this is similar to how we navigate in real life. The routing table is just a 'roadmap' that tells a computer/router where to go to get to other devices on the network. What is shown in the screenshot is a routing table from a computer.

Then, YLearn offers a broader overview of naming conventions in general and how to think about them: Together with mask 255.0.0.0 it gives you a hint that whole class A of addresses starting with 127.*.*.* will contain loopback addresses. And they are not both loopback adresses.ġ27.0.0.1 is a loopback address 127.0.0.2 is a loopback address 127.0.0.3 is a loopback address and so onġ27.0.0.0 is a network address. First, Mmmc offers this succinct overview: Two SuperUser contributors jumped in to help solve the mystery.
