ASO AC delivers Recommended Draft RIR Governance Document to NRO EC
The ASO AC has delivered the ASO AC Recommended Draft RIR Governance Document to the NRO EC for its consideration.
Hooray for the sockets interface
In 1983, BSD 4.2 introduced sockets, treating network communication like file I/O. This simplification sped UNIX adoption of shared protocols and services, marking a key turning point in modern networking.
Secure by default: How ‘HSTS-Enforced’ could finally close the web’s oldest backdoor
Guest Post: The current web still relies on a legacy assumption that website should be accessible over unencrypted HTTP unless it explicitly signals otherwise. HSTS-Enforced builds on top of HSTS by inverting its security model.
The delicate art of cryptographic maintenance: When small certs break big chains
Around mid-2026, we began receiving user complaints about certificate validation failures. The failure wasn’t a single bug, but the collision of optimization and slow distribution.
[Podcast] DNS query duplication
Why does APNIC Labs experimental systems see almost all DNS queries twice or more?
Bringing APNIC closer to Members: SANOG to host next APNIC Sub-Regional Forum
APNIC’s next Sub-Regional Forum at SANOG in Kathmandu, Nepal, will bring Internet operations, policy, and community discussions closer to Members in South Asia.
APNIC 62 workshops build practical skills for modern network operations
APNIC 62 features three hands-on workshops that help network professionals automate operations, strengthen security, and deploy next-generation routing technologies.
IPv6 address planning: From ‘bit conservation’ to ‘elegant alignment’
Guest Post: When planning IPv6 addressing schemes, many engineers still carry over habits from the IPv4 era. The instinct is to conserve every possible bit and to compress region, service, and network type information into the smallest space that meets current needs. While this approach once made sense, it is poorly suited to IPv6.
Rethinking non‑access stratum timers for LEO satellite constellations in 5G and beyond
Guest Post: AstroTimer starts from a simple but important question: Can we compute NAS timers directly from LEO‑specific conditions, such as path length, link variability, and NF load, using a closed‑form, low‑cost model?
