IPv6 native traffic: How to push past 80% at home

Mon, 16 Mar 2026 00:00:00 +0000

With Debian ISO downloads forcing native connectivity, home networks can push IPv6 traffic above 80% as proven by Terry Sweester.

Active path verification stops blackhole errors

With RPKI adoption for leased prefixes surging from 29.9% in 2021 to 71.0% by late 2024, validating blackhole routes remains dangerously ambiguous. Blindly propagating these filters across all points of view often collapses complex routing topologies into a single, erroneous perspective that the source ASN never authorized.

Blackhole route checks: Stop accidental outages

With the SDN market projected to grow over 4x in the next decade, automating blackhole route validation is no longer optional. Reliance on legacy Internet Routing Registry (IRR) data creates critical vulnerabilities where unauthorized traffic suppression can cascade across networks due to blind acceptance of unverified path requests.

Blackhole validation must use active path data now

Sun, 01 Mar 2026 00:00:00 +0000

Strict path verification now overrides legacy IRR checks, as 2026 mandates enforce penalties for invalid blackhole route requests. The industry has decisively shifted from voluntary filtering to rigid enforcement protocols, where regulators and Tier-1 providers penalize operators who fail to validate traffic forwarding paths accurately. Job Snijders confirmed in a March 2026 NANOG discussion that modern blackhole validation must discard reliance on unverified IRR data, noting that such arbitrary lists lack the provenance required for today's compliance environment. Instead, operators must verify if IP traffic is actively forwarded to the requesting entity before honoring any mitigation request.
