PC Speak: An Abney and Associates Internet and Technology Research Lab Presents the IPv6

Internet Protocol version 6 is the most recent update of the IP, the main communications protocol that holds the whole Internet. It is created to supplant the older Internet Protocol version 4 that is still in use on most of the web traffic until today. IPv6 was formed by the IETF (Internet Engineering Task Force) as a solution for the IPv4?s imminent address shortage.

For every device that connects to the Internet, it needs an IP address ? a binary number assigned to it to enable communication with other devices. And with the quick turnout of Internet-capable devices today, the current IPv4 protocol is running out of addresses that we could use.

An IPv6 address is composed of 8 sets of 4 hex digits, separated by colons like the following:

3002:1ca8:74b2:1153:1010:7b1d:1480:6225

Because IPv6 uses a 128-bit address, as opposed to IPv4?s 32-bit, the former can have roughly 4.8 x 1028 addresses for every person alive ? and it would be a fraud to have this quantity run out any time soon. The problem is, because of the incompatibility of the 2 protocols, transition from IPv4 to IPv6 can be difficult.

World IPv6 Launch was done on June 6, 2012 where main ISPs supported the use of IPv6 addresses to some of their users. But even as the campaign for widespread adaptation of IPv6 is taking off, its usage has only reached a peak of 0.2% traffic which was during the launch.

IPv4 is the first version of the IP for public use. An IPv4 address is shown as 4 numbers, each of which range from 0-255 (with 8 bits every number, its total comes to 32 bits). Therefore, IPv4 is capable of over 4 billion addresses. Exhausting the addresses has not been a concern at first because it was only meant to be a test in the ARPANET and not for public use.

In 2008, the DNS has been configured for the use of IPv6 and since then, it has been deployed on main commercial OS. Its first use was demonstrated on the Summer Olympic Games of the same year, the largest usage since its inception.

Numerous transition processes need to be employed to enable hosts that only supports IPv6 to be reachable from IPv4 ones or to make IPv6-only networks and hosts communicate in an infrastructure that only supports IPv4. However, those measures must be done temporarily as IPv6 gradually replace IPv4. One such transition method is to use tunneling to enclose IPv6 traffic in IPv4 infrastructure, but this is only applicable as a short-term solution due its high latency.

    • If Valve refused to let them make the case, I wonder if they've already partnered with someone else to do it? The fact that they didn't seek permission/licence before diving straight in is incredible though
    • OpenClaw now has native mobile apps on iOS and Android by Karthik Mudaliar OpenClaw, the viral open-source personal AI agent, now has its own mobile app, available on both Android and iOS. Users can pair the app with an existing OpenClaw gateway and can start using new mobile-native features that are now available on the app. The app supports all the existing features you'd already have seen on OpenClaw's TUI, as well as some more, such as real-time and background Talk mode, action approvals, sharing from iOS, and optional access to device capabilities such as camera, screen, location, photos, contacts, calendar, and reminders. These features are available on both the Android and iOS versions of the app. What's important with these apps is that they don't run OpenClaw on your phone, but are actually just companion apps that require a running OpenClaw Gateway on an existing device, on macOS, Linux, or Windows via WSL2. To pair the app with your existing OpenClaw gateway, users need to run the command "/pair qr" on the TUI or existing chat interface, which brings up a QR code. Users can then scan this QR code to pair it up with the mobile app. There's also an option to manually pair the app by entering the host and a port. Previously, OpenClaw had been available on phones via WhatsApp, Telegram, Slack, Discord, Microsoft Teams, Matrix, and others. Now, with a native mobile app, the interface is much cleaner and more focused on just the OpenClaw, of course, with the added support for camera, screen, location, and more. It's important to note that OpenClaw comes with its own security warnings. There's always a chance of prompt injection with these tools, so users are recommended to double-check authentication, tool policy, sandboxing, and execution approvals rather than prompts alone. For users well-versed with the AI harness, a native mobile app makes it easier to approve an automation, share a link, use voice, or let an agent react to phone-side context.
    • Google pitches Spanner as one database for all AI agents with these new featues by Karthik Mudaliar Google Cloud is introducing new features within Spanner, its distributed database, as a place where enterprises should keep their data, using which AI agents could make smarter and better decisions. In a detailed blog post, Google highlighted quite a few features coming to Spanner, including relational data, graph relationships, vector search, key-value access, full-text search, and operational analytics together in one database architecture. Google says that today's systems aren't well-made for AI agents. There could be data that is present in one system, search indexes in another, embeddings in a vector database, and relationship data in a graph database. This fragmentation isn't great for AI agents to do their jobs because they don't have access to all of this data in one place. This is where Google is positioning Spanner as a solution. Spanner is already a globally distributed relational database with strong consistency, and Google wants its customers to see it as a broader data layer for AI applications. The company introduced something called Spanner Graph, along with integrated vector search, full-text search, a Cassandra-compatible key-value endpoint, and a columnar engine for analytical queries on operational data. Google also added that its ScaNN-powered vector search can support indexes with more than 10 billion vectors, while the columnar engine can make some analytical scans up to 200 times faster. All of this isn't just exclusive to the Google Cloud Platform, and there's support for multi-cloud as well. This comes via Spanner Omni, which Google says is a downloadable, containerized version of Spanner that can run on Kubernetes and in environments outside Google Cloud, including Microsoft Azure and AWS, and even on-premises infrastructure as well as edge deployments. Google says that customers who are interested in the full-featured edition should contact the company, and there's no word on commercial availability or separate pricing. Those interested can read the full blog by Google Cloud, which details these features individually.
