Reflections on a Transforming Interconnection Ecosystem
Flavio Luciani and John Souter’s new analysis shows the global peering market is not contracting but evolving. While mature regions exhibit modest dips in ASN counts, overall IXP capacity continues to rise, driven by traffic consolidation and the growth of private network interconnects. The study highlights divergent regional trends—steady expansion in Latin America, stabilization in Europe, and mixed progress in Africa and Asia‑Pacific. Crucially, IXPs are broadening their service portfolios, hosting banks, public administrations, and edge‑focused applications, positioning them as strategic infrastructure beyond simple traffic exchange.
On Misusing Transparent DNS Forwarders For Amplification Attacks
Researchers have identified transparent DNS forwarders as a potent, overlooked vector for reflective amplification attacks. Unlike traditional open resolvers, these forwarders relay queries without rewriting source IPs, allowing attackers to exploit shielded recursive resolvers and bypass rate‑limiting controls. Weekly Internet‑wide...
