DHCP is great for getting machines on the network with a minimum of fuss. However, it can also make remote administration a pain because you never know which IP you’re supposed to be SSHing into. [Philipp] ran into this problem quite often, so decided to whip up an app to make things easier. At it’s […]
VPNs, Virtual Private Networks, aren’t just a good idea to keep your data secure: for millions of people living under restrictive regimes they’re the only way to ensure full access to the internet. What do you do when your government orders ISPs to ban VPNs, like Russia has done recently? [LaserHelix] shows us one way […]
Although we have many types of networking equipment with many unique names, at their core they can usually be reduced to just a computer with some specific peripherals. This is especially the case for something like a router, a device found in just about any home these days. Certain consumer-grade routers may contain something special […]
As literally everything ought to be able to play DOOM in some fashion, [Adam Rice] recently set out to make the venerable DNS finally play the game after far too many decades of being DOOM-less. You may be wondering how video games and a boring domain records database relate to each other. This is where DNS […]
If you’ve ever run a game server or used BitTorrent, you probably know that life is easier if your router supports UPnP (Universal Plug and Play). This is a fairly old tech — created by a standards group in 1999 — that allows a program to open an incoming port into your home network. Of […]
If you have ever read science fiction, you’ve probably seen “alternate history” stories. You know, where Europeans didn’t discover the New World until the 19th century, or the ancient Egyptians stumbled upon electricity. Maybe those things happened in an alternate universe. [BillPG] has an alternate history tale for us that imagines IPv6 was shot down […]
A quiet shift over the last couple of decades in many places has been the disappearance of the traditional copper phone line. First the corded landline phone was replaced by cordless, then the phone migrated to a mobile device, and finally DSL connections are being supplanted by fiber. This leaves copper-era infrastructure in houses, which […]
The Internet has spoiled us. You assume network packets either show up pretty quickly or they are never going to show up. Even if you are using WiFi in a crowded sports stadium or LTE on the side of a deserted highway, you probably either have no connection or a fairly robust, although perhaps intermittent, […]
An effective currency needs to be widely accepted, easy to use, and stable in value. By now most of us have recognized that cryptocurrencies fail at all three things, despite lofty ideals revolving around decentralization, transparency, and trust. But that doesn’t mean that all digital currencies or payment systems are doomed to failure. [Roni] has […]
Wi-Fi! It’s everywhere, and yet you can’t really see it, by virtue of the technology relying on the transmission of electromagnetic waves outside the visual spectrum. Never mind, though, because you can always build yourself a Wi-Fi analyzer to get some insight into your radio surroundings, as demonstrated by [moononournation]. The core of the build […]
