The report says RPKI coverage rose from 54% to 70% in a year and explains how route-origin validation addresses mistaken or malicious BGP announcements. Engineers operating networked services should understand this evolving layer of internet routing security.

What: RPKI lets IP-address block holders publish signed Route Origin Authorizations naming the networks allowed to announce their prefixes.
How: RPKI-valid routed prefixes rose from 54.0% in September 2025 to 70.3% in September 2026; a typical invalid route reached just two vantage points.
Why it matters: Network operators can reject announcements that fail RPKI checks, helping limit the spread of routing mistakes and hijacks.

Network operators compare routing announcements with ROAs and can reject invalid routes. Sketched from the article's own text.
