### AI overview

This report examines changes in Central Asia's Internet connectivity since CAPIF 1. It describes more direct regional routes, expanding IXPs, stronger routing security and new links toward Pakistan, China, Azerbaijan and Europe, while noting persistently low IPv6 adoption and continued, though reduced, reliance on routes through Russia.

### Source excerpt

Central Asia's Internet looks very different than it did back at CAPIF 1. We trace the rise of direct regional routes, stronger routing security and new connectivity options - along with the gaps that remain.

### AI overview

Airtel has told customers it plans to begin rolling out RPKI Route Origin Validation on 22 September 2026. The article examines 726 RPKI-invalid routes in Airtel's table, including 108 IPv4 and 618 IPv6 routes, and discusses their visibility outside India.

### Source excerpt

Just back from Mumbai after APNIC 62 and Equinix's India Peering Forum. On excellent news: Airtel has started sending emails to its customers about RPKI RoV (Route Origin Validation). As per the mail, Airtel will start RPKI RoV soon and has mentioned 22 Sep 2026 as the timeline when they will start rolling out RoV. This is excellent news on the routing security front, and kudos to Airtel (AS9498) for taking the lead here among other large Indian backbones. This brings up the important question of how many routes exist in their table which are RPKI RoV invalids as of today? Looking at their announcements, I see the following: RPKI Valids: 33,735 RPKI Unknown: 4632 RPKI invalids: 726 This is for their table, including downstream routes. One can view the complete list of those 726 invalids, including prefix and AS_PATH here. One interesting thing here is that out of 726, 140 are from Airtel fixedline AS24560 and 122 are from Airtel Mobility. In terms of address family, there are 108 invalids from IPv4 and 618 from IPv6. How many of these invalids are single-homed vs multi-homed? This is important to check, as often the argument against RoV given by various operators in past was that they were losing traffic to their competitors. When I checked, I do not see any of these prefixes visible outside of India behind a transit-free / tier 1 network without AS9498 in the path. It could be because Tata Comm AS6453 drops RPKI invalid already & most of these are not dual-homed via Jio AS64049. So unless a less specific RPKI valid announcement is there, these are anyway largely blackholed for now by networks & IXPs doing RoV outside of India. Let's hope other Indian backbones also start doing RPKI RoV soon. Happy routing! 😀

### AI overview

The article explains how to assign predictable management IP addresses to virtual network devices. It contrasts manual console-based setup with automated assignment through orchestration, containers, DHCPv4/DHCPv6, custom Vagrant boxes, and IPv6 mechanisms such as SLAAC.

### Source excerpt

It goes without saying that if you want to configure (virtual) network devices with any semi-sane configuration mechanism1, the device must have a working IP address. Here's the time-honored method2 to assign an IP address to a virtual network device: Start the virtual machine (using a GUI)3 Open a new window: either a telnet session to the virtual console port or a full-blown virtual console (GUI) session. Manually configure the IP address, the SSH server, and the user credentials on the first interface. Read more ...

The article examines how IPv6 addressing and policy mechanisms may need to evolve for space networking. It argues that terrestrial assumptions break down beyond low Earth orbit and calls for addressing policy questions now, including through the proposed EXPANSE working group.

### Source excerpt

A large chunk of IPv6 is heading for space, and every policy question about it is currently going to be deferred to the RIR communities. This article outlines what those questions look like, and argues why now is the time to start asking them.

### AI overview

A technology reading roundup touching on how Internet Exchange Points affect Internet performance, the meaning and use of industrial Modbus packet data, and the societal risks and benefits associated with IPv6. It also briefly evokes robotic pizza preparation.

### Source excerpt

Information is not meaningful simply because it exists or because it is improbable. It becomes meaningful only if there exists a system that can interpret it and use it to perform a function. At first glance, asking whether Internet Exchange Points (IXPs) make the Internet faster may seem almost provocative at a peering forum. Surely the answer is simply 'yes'? If you're dealing with industrial protocols, you'll certainly have seen Modbus packets in your network. But what are these packets used for, and what data do they contain? Yet I have become increasingly concerned that, in the case of IPv6, we are evaluating the technology almost entirely from the perspective of what it allows networks to do, while giving insufficient attention to what it may allow network operators, corporations and governments to do to their users and if the benefits outweigh the risks. The future of fast food was supposed to look something like this: walk into a restaurant, place an order, and watch a robot assemble your pizza with machine-like precision.

### AI overview

This article explains how Pesto, a companion tool from the passt project, addresses Rootless Podman's inability to preserve incoming client source IPs on bridge networks. Pesto updates pasta's forwarding table so traffic reaches containers without source-address rewriting, while retaining existing port-mapping capabilities. The article also documents configuration steps, traffic flow, supported networking features, and limitations when switching from the current forwarder.

### Source excerpt

Rootless Podman has a long-standing limitation reported since 2020: containers on bridge networks can't see the real source IP of incoming connections. The `rootlessport` userspace proxy rewrites the source to the container's own subnet address, breaking IP-based access control, logging, and rate limiting. Pesto, a new companion tool from the passt project solves this. Pesto [...]

### AI overview

The article explains an IPv6 Neighbour Discovery asymmetry: a host can reach its router immediately after configuring an address, while the router may not yet know how to reach the host. This can delay or drop the first return packets. GRAND addresses the gap by having the host proactively advertise its address, and the article describes an implementation of this mechanism in FreeBSD.

### Source excerpt

There is a subtle asymmetry in IPv6 Neighbour Discovery: a host knows how to reach its router before the router necessarily knows how to reach the host. GRAND fixes that asymmetry by making the host proactively advertise its address, and I implemented that mechanism in FreeBSD.

### AI overview

The article examines the IPv6 loopback-prefix problem in high-speed routers and data-center switches. OSPFv3 requires loopbacks to be advertised as /128s, which can increase forwarding hardware demands when /64 addressing is preferred. It compares vendor behaviors and suggests IS-IS or BGP as possible alternatives.

### Source excerpt

Remember the sage advice to simplify your life and use the IPv6 /64 prefixes everywhere? Not only does it make your life simpler (and wastes immesuarably less address space than the crazy "let's assign /64 to every device" stupidity), it also reduces the hardware requirements in your high-speed routers layer-3 switches. You see, doing lookups on 64 bits uses half the silicon it takes to do lookups on 128 bits. Alas, some people never got the memo. OSPFv3 standard clearly states in one of the bullets in section 4.4.3.9 that the loopback prefixes should always be advertised as /128s regardless of what's configured on the interface.

### AI overview

A developer reading roundup covering Internet infrastructure, synchronization of replicated data, IPv6-only networking, IPv4 dependencies, ARP, an IETF proposal, 5G control-plane timers, modern machine-learning pipelines, and the integration of AI into everyday applications.

### Source excerpt

Today's Internet runs on a vast infrastructure of replicated data, and the difference between order and chaos lies in maintaining consistency through synchronization across the many distributed points where that data is published. IPv6-only networks often still depend on IPv4 subnets and ARP. This article introduces an IETF proposal to eliminate both. Traditional software engineering approaches reliability as a binary state of uptime and downtime. Modern ML pipelines render this paradigm obsolete. Yet while the radios and protocols largely reuse terrestrial 5G designs, one small but crucial component has been left behind: The control plane timers that quietly govern how registration, mobility, and session procedures behave under real-world conditions. Apparently, nearly all of them have reached the same conclusion. I don't merely need AI occasionally. I need it waiting inside every search bar, messaging app, music player, and document reader I already use.

### AI overview

The article describes a self-service peering portal that uses PeeringDB OAuth to authenticate users, verify ASN update rights, and offer exchanges where both networks are present. Requests create disabled sessions for manual approval, with inherited filtering and validation policies, notifications, and approval-based removal.

### Source excerpt

Peering requests used to be mail ping-pong. Now you log in with PeeringDB on the peering page, pick an exchange, and the session is waiting for my approval.
