Guest Post: RPKI has made real progress against prefix hijacking. But when you map every known class of BGP attack against the defences that exist, four of them turn out to sit entirely outside cryptographic validation — handled with local filters, static thresholds and reactive response.
The APNIC 62 Open Policy Meeting will consider a diverse set of policy proposals covering IPv4 management, IPv6 allocation practices, and Internet abuse handling.
Geoff Huston explains the reasons for the CIDR Report, what’s in it, and shares some thoughts as to its usefulness to the Internet routing community today.
At APNIC 61 in Jakarta, the Policy SIG discussed proposals to reduce minimum IPv6 and increase maximum IPv4 delegations, highlighting tradeoffs between efficiency, record-keeping, and network planning. A Policy 101 session also introduced newcomers to APNIC’s consensus-driven policy process.
What IPv4 and IPv6 addressing in 2025 tells us about the changing nature of the network.
Geoff Huston explores changes to the stability of the routing system in 2025.
