AS53605 PHOEN-56
Unclassified ARIN
Summary
PhoenixNAP
hosting datacenter infrastructure
PHOEN-56 is operated by PhoenixNAP LLC.
What it's used for
- The address space carries data center infrastructure, evidenced by the netname
SC-ASHassigned to both announced prefixes. - The AS announces 1536 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a focused hosting or infrastructure role rather than a transit provider.
- Traffic from this AS consists of web/API endpoints, dedicated servers, and cloud workloads hosted in PhoenixNAP's data centers.
Notable
- Registrants for both prefixes are PhoenixNAP LLC, matching the AS holder.
- PhoenixNAP is a global IT infrastructure provider offering bare metal cloud, dedicated servers, and network services.
- The inventory consists of two contiguous IPv4 blocks in the 199.201.104.0/22 and 199.201.108.0/23 range, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 440 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
