This simple tutorial will show you two simple ways of sending messages over a local network. If you doesn't have the Internet connection or prefer to use local messaging app, check guide and follow these simple steps.

No individual device on your wireless network may run that much faster, but your total speed will increase.

Moving into software defined networking and devops? Here's the skills you need and how to acquire them

In this video tutorial, we'll show you how to set up a LAN messaging application for secure communication over a company network. You can get Windows, Android and Mac versions of the messenger. First of all, install the LAN messenger to every device connected to your office network. The chat app automatically detects all other users available. Click any name and start sending messages, transfer files or even get remote access to co-worker PC. It's simple to understand the program interface.

The new cables are based on Intel's Silicon Photonics technology that pushes 25Gbps across each fiber. Last year, Intel demonstrated speeds of 100Gbps in each direction, using eight fibers. A new connector that goes by the name "MXC" holds up to 64 fibers (32 for transmitting and 32 for receiving), enabling a jump to 800Gbps in one direction and 800Gbps in the other, or an aggregate of "1.6Tbps" as Intel prefers to call it. (In case you're wondering, MXC is not an acronym for anything.)

In April, ARIN, the (North) American Registry for Internet Numbers, announced that it had reached "phase 4" of its IPv4 countdown plan, with fewer than 17 million IPv4 addresses remaining. There is no phase 5. APNIC, the Asia-Pacific registry, reached the 17 million (one "/8" or 2^24 IPv4 addresses) threshold three years ago, and the RIPE NCC in Europe less than two years ago.

DSL, slow old DSL, may yet come back to compete with cable and fibre for the last-mile internet speed championship.

Some people may be trying to spend less time distracted on social media this year, but for freelancers, staying active on networks like Facebook and Twitter is one of the smartest moves they can make.

Cody Spafford found both solace and redemption in the kitchen of Seattle’s most celebrated restaurant. What turned a promising chef into a bank robber?

If you aren't intimately familiar with software defined networking, don't fret. Only 10% of 450 IT practitioners at a recent Network World event raised their hands when asked if they understand SDN. But if the emerging technology lives up to its promise to redefine networking as we know it, there is no time like the present to dig in and learn more.

Powerline devices route data through your electric cables, offering an alternative when Wi-Fi fails. We review 4 of the latest kits to see how well they work.

A bunch of home gateway vendors, presumably sourcing their firmware from the same place, can be hijacked using depressingly common hard-coded logins. As the Carnegie-Mellon CERT states, the vendors involved are ASUS and ZTE in Asia, European vendors Digicom and Observa Telecom, and carrier Philippine Long Distance Telephone (PLDT), which was presumably house-branding the kit.

North America has officially run out of its stock of old net addresses.

Shodan caught using time-keeping servers to quietly harvest IP addresses.

With more speed available and hardware that can't adapt, DIY builds offer peak performance.

Founded in 2001, San Jose-based Cavium is a fabless semiconductor designer that produces chips for the likes of Cisco, F5, Aruba, Netgear, Nokia Siemens, Juniper, Samsung, LG and others. Its Octeon SoCs turn up in cellphone base stations, and edge and core switches and routers, where MIPS is a traditional architecture.

When your internet goes out, resetting your wi-fi router and cable modem often seems to fix the problem. Instead of getting up from the couch to fiddle with power cords, why not let a tiny outlet adapter power cycle your hardware for you?

Over the past year or two, someone has been probing the defenses of the companies that run critical pieces of the Internet. These probes take the form of precisely calibrated attacks designed to determine exactly how well these companies can defend themselves, and what would be required to take them down. We don't know who is doing this, but it feels like a large a large nation state.

The Homebrew is still near the top of the class, but one off-the-shelf router bests it.

Powered by radios in trees, homegrown network serves 50 houses on Orcas Island.

The rules require providers to ask your permission before sharing your data.

You should consider uninstalling WOT right now. Why? Because Web of Trust has been caught collecting and selling user data. Even worse, this data hasn't always been successfully anonymized.

A new report has surfaced that Apple is getting rid of its division for wireless routers, signaling that AirPort is on its way out the door for good...

Network Time Protocol is how the computers you depend on know what time it is (this is critical to network operations, cryptography, and many other critical functions); NTP software was, until recently, stored in a proprietary format on a computer that no one had the password for (and which had not been updated in a decade), and maintained almost entirely by one person.

A flaw in Netgear routers is 'trivial' to remotely exploit -- R7000, R8000 and R6400 -- maybe more. US-CERT advised discontinuing use unless Netgear issues a fix. There's a way to test if your router is vulnerable and an unofficial temporary fix.

Mesh networking has finally come to small businesses and offices. Here's why that matters.

Your home Wi-Fi performance will soon get much better thanks to new Wi-Fi chips that Qualcomm announced today, the IPQ8074 system-on-chip (SoC) for broadcasters (routers and access points) and the QCA6290 SoC for receivers (Wi-Fi devices). They belong to the first end-to-end commercial Wi-Fi portfolio to support the all-new 802.11ax standard.

The good news is that it doesn't have to suck, if you build it out properly.

A giant outage of Amazon Web Services and other recent accidents offer an opportunity to reflect on the perilous architecture of the web.

Learn how the global DNS system makes it possible for us to assign memorable names to the worldwide network of machines we connect to every day.

An industry consortium called MulteFire wants to help you build your own LTE-like network that uses the Wi-Fi spectrum, with no need for carriers or providers.

Today, no company would consider using anything except Ethernet for its wired local-area network. But it wasn't always that way. Steven Vaughan-Nichols tracks the history of Ethernet, and its once-upon-a-time networking protocol competitors.
