NAT type describes how easily a gaming device can communicate over the internet, with Open, Moderate and Strict tiers on Xbox and PC (and equivalents on PlayStation and Switch). Open allows unrestricted connections but isn't practical or secure for most setups since it bypasses router protections, while Moderate works behind a router and Strict blocks necessary ports, causing matchmaking issues.
IPv4's 32-bit addressing scheme, which created about 4.3 billion addresses, ran dry years ago, with North America's allocation exhausted in 2015. ISPs have papered over the shortage using carrier-grade NAT, which shares public addresses among groups of customers but can break peer-to-peer connections like online gaming. IPv6, standardized in 1995 with 340 undecillion possible addresses, is meant to solve this permanently but currently coexists with IPv4 rather than replacing it, with Google measuring global IPv6 usage at just under 51 percent.
Google Summer of Code participant Artem Belan spent summer 2026 reworking racoon2, NetBSD's IKEv1/IKEv2 key exchange daemon, fixing RFC 7383 message fragmentation, adding NAT-OA payload handling for IKEv1 Quick Mode, improving IPv6 support, and building an automated test suite. The work was merged upstream via pull requests #13 through #39 on the project's gsoc2026 branch between June and September 2026.
Meta released Muse Gadgets, an open-source project providing firmware and a Linux SDK so developers can build custom hardware that connects to its Muse AI agent, with suggested projects like e-ink displays or HDMI stick devices. The company also built its own gadget, Muse Home Link, a USB-C device that lets Muse control smart home devices, and is giving away 5,000 units free to subscribers while supplies last.
Meta has opened a project called Muse Gadgets, offering developers open-source firmware and a Linux SDK to build their own devices powered by its Muse AI agent. The company also released its own example, the Muse Home Link, a USB-C dongle that connects Muse to home networks and smart devices; Meta says it has produced 5,000 units to give to Muse subscribers. Nat Friedman, head of product for Meta's superintelligence labs, announced the initiative and set up a Discord community for developers.
Social media users, including a Redditor, allege that Meta's new consumer AI agent Muse is built directly on the OpenClaw platform, pointing to identical core file names like SOUL.md and near-identical personality-guiding text. Meta's Nat Friedman, head of product for Superintelligence Labs, says Muse was built 'from scratch' but was 'heavily inspired' by OpenClaw, and that his team deliberately reused file names and phrasing they believed OpenClaw's creator had gotten right.
Tailscale published a technical update on performance work across its network, including multi-queue support for app connectors, subnet routers, and exit nodes expected in the second half of 2026. The company also previewed throughput and memory overhead improvements coming to upcoming stable client releases, building on prior gains such as 10Gb/s wireguard-go throughput and 4x UDP throughput via segmentation offloads.
Meta Superintelligence Labs product head Nat Friedman said on X that Muse, Meta's AI product, was 'heavily inspired' by the open-source OpenClaw but was 'built from scratch.' The admission followed viral claims from users, including AI app co-founder Ansh Nanda, that Muse resembled a consumer-friendly version of OpenClaw, citing shared file structures like SOUL.md.
Security researchers found that Android's public NAT-T socket-keepalive API allows ordinary apps to send UDP packets directly to a router, bypassing Always-on VPN and 'Block connections without VPN' protections. Tests on a Pixel 8 Pro, Samsung SM-F966B, and Nothing A059, all running Android 16, confirmed that keepalive packets reached the physical gateway outside the VPN tunnel, with one device sustaining a leak for over 24 hours. The root cause traces to changes in Android's startNattKeepaliveWithFd function, where validation checks tying the socket to the caller's VPN policy were added and later removed.
When a home network has both an ISP-supplied gateway and a personal router or mesh system, leaving both in default settings can create double NAT, since the ISP gateway keeps routing traffic even when connected to another router. The fix is to either put the ISP gateway into bridge mode so it stops routing, or switch the personal router into access point mode so it only extends Wi-Fi while the gateway keeps routing.
A programming-focused post lists dozens of widely believed but often incorrect assumptions about local area networks, covering NAT behavior, MAC address uniqueness, DHCP configuration, protocol assumptions, and reachability between devices on the same subnet. The list format deliberately states each falsehood as if true, following the popular 'Falsehoods Programmers Believe' meme style used for other technical domains.
Tailscale has launched tailcat, an open-source Go package and CLI tool that lets developers move data between two points using the company's underlying network technology—WireGuard encryption, NAT traversal, and DERP relay servers—without any of Tailscale's account system, control plane, or administrative layer. It functions like the classic netcat utility but routes traffic through Tailscale's magicsock networking stack, and can run entirely independent of Tailscale as a company if users host their own DERP relay server.
