About this network

ARIN-EDGEPRIZM-ASN belongs to EdgePrizm, a content delivery network built by former Limelight Networks engineers out of acquired Limelight CDN assets. The low AS number reflects a reassignment to a modern holder, not an early-internet allocation.

What it's used for

• CDN edge delivery, aimed at application performance, transactional workloads, and gaming rather than large-scale video streaming.
• Edge security and acceleration services for enterprise customers.

Notable

• Small announced footprint (a couple of thousand IPv4 addresses), typical of a CDN that concentrates a lot of traffic behind a small, anycast-heavy set of prefixes.
• Presence is spread across points of presence in North America and Europe, with expansion into other regions, so geolocation of a single address here is unreliable by design.

Interesting

• The company launched publicly in 2025, so an IP in this AS is edge infrastructure of a young CDN despite the vintage-looking AS number.
