About this network

An Akamai Autonomous System (AKAMAI-NOMINUM-ASN) tracing to Akamai's 2017 acquisition of Nominum, a carrier-grade DNS and DNS-security vendor. It backs recursive DNS and threat-protection services rather than general CDN caching.

What it's used for

• Carrier and enterprise DNS resolution plus DNS-based security filtering (malware, phishing, and data-exfiltration blocking).

Notable

• Operated by Akamai, a major CDN/edge provider; this block is DNS/security infrastructure specifically.
• Sibling of Akamai's CDN ASNs — see AS23454 and AS24319.

Interesting

• Nominum's platform handled well over a trillion DNS queries per day, which Akamai folded into its security threat intelligence.
