Geoff Huston's report shows how CIDR saved us from wasting 65,536 addresses per block. Learn why this matters for your 2026 IPv4 strategy.

Stop managing duplicate firewalls. With 65% of enterprises adopting cloud, centralize your ingress inspection to eliminate configuration drift today.

IPv8's single Zone Server creates a massive blast radius. With Google showing over 50% IPv6 access, this rigid draft lacks the distributed durability we need.

APNIC's 2026 study shows always-on scrubbing dominates. Learn why five-minute BGP intervals reveal the end of reactive defense for major networks.

With cybercrime hitting $10.5 trillion, I urge networks to swap manual registry entries for cryptographic RPKI validation today.

Akamai's 4,000 edge PoPs struggle when DNS resolvers hide true user location, causing real latency issues for streaming content in 2026.

With optical fiber holding 90% of the market, I argue that Pacific infrastructure must prioritize local peering over raw international capacity to survive.

Deploy Akvorado on a 6-core NUC to visualize IPv6 traffic. Learn how SNMP and NetFlow v9 reveal hidden ASN data in SOHO networks today.

Stop using public gateways. Discover how 3 Availability Zones create the mandatory foundation for compliant, isolated AI workflows today.

Running 55K in-kernel requests reveals why eBPF fails complex apps. I analyze the runtime constraints blocking true network acceleration today.

ARIN confirms a 12-hour outage on March 28 where write APIs reject traffic. As a CEO managing IP assets, I advise halting automation scripts now.

AFRINIC's legal fight with Cloud Innovation blocks IPv4 for 56 countries. I analyze how this paralysis impacts 2,400 members and market stability.

With TWNIC hitting 98% IPv6 RPKI validity, I see how seven NIRs are finally turning administrative coordination into a real defense against route hijacking.

Italo Cunha notes maintaining 16 route6 objects for a single /44 block proves legacy IRR filtering cannot scale for modern operators.

Stop linear scans. With traffic hitting 450 exabytes by 2027, switch to ASSET origin checks to secure your DFZ filters now.

I break down the APNIC Fellowship's dual tracks, noting the tight window closing on 13 March 2026 for this critical capacity building.

The new RIPE NCC course spans 24 hours to fix critical gaps in IPv6 infrastructure design and addressing architecture for modern networks.

The NRO NC reviewed feedback from five mailing lists to shape the 2026 framework. See how global consensus drives regional IP stability today.

Applications for the ARIN 57 Fellowship close 26 January 2026. I break down how to prove your NRPM knowledge before AI takes over policy work.
