About this ASN.

Updated  ·  Confidence: High

AS63949 is the former Linode IaaS/VPS network, now operated as Akamai Connected Cloud after Akamai's 2022 acquisition, registered through APNIC to Akamai Technologies. It is important to label this network explicitly: although it is a sibling of the Akamai CDN ASNs (AS20940 and AS16625) under shared ownership, it behaves very differently — this is developer-focused Linux VPS, Kubernetes, and object storage across roughly eleven global regions, not CDN edge delivery. It originates around 347 IPv4 prefixes (~1.3 million addresses) and ~94–99 IPv6 prefixes, is present at about 25 IXPs, and in newer 2023-plus compute regions is reachable only via Akamai's AS20940. CAIDA sees it as a leaf with seven providers and no customers. A well-known legitimate host on this network is scanme.nmap.org (45.33.32.156), the Nmap project's sanctioned scan-practice target. For triage, the multi-tenant ephemeral-IP caveat applies — a single IP can host many unrelated VMs over time and is reassigned frequently, so reputation must bind to the current tenant. Because it is the former Linode VPS network, it appears in honeypot and scanning datasets, and Cloudflare Radar has recorded a Linode/Akamai BGP route leak from a Miami data center attributed to an automated routing-policy configuration error.

Security/abuse context (DATED, NEUTRAL — multi-tenant)

one IP can host many unrelated VMs over time; attribute to tenant. As the former Linode VPS network it appears in honeypot/scanning datasets (some Tor/anycast tags per IPinfo); Cloudflare Radar recorded a Linode/Akamai BGP route leak from a Miami data center attributed to an automated routing-policy configuration error — radar.cloudflare.com/routing/as63949, ipinfo.io

Network & routing

Network type
hosting-VPS — DISTINCT from Akamai CDN ASNs AS20940/AS16625 [Confirmed]
Size
~347–348 IPv4 prefixes (~1.3M addrs), ~94–99 IPv6; ~2.9M estimated users (APNIC) — bgp.he.net / bgp.tools (2026-06)
Routing/peering
all PNI via Akamai AS20940; in newer 2023+ compute regions reachable only via AS20940 (PeeringDB); ~25 IXPs; RPKI ~338 v4 / 95 v6 valid, 3 v6 invalid — bgp.he.net, peeringdb.com/asn/63949
Notable usage
former Linode IaaS/VPS — Linux VPS, Kubernetes, object storage across ~11 regions; hosts scanme.nmap.org (45.33.32.156), the Nmap project's sanctioned scan-practice target — linode.com / akamai.com
