What it's used for
- The address space carries data center infrastructure, evidenced by the reverse DNS entry
37.140.233.0.phoenixnap.comand netnamesUS-PNAP-20120301. - The AS announces 1536 IPv4 addresses across 2 prefixes with 1 observed neighbour, indicating a hosting or colocation role rather than transit.
- Traffic from this AS consists of server workloads, cloud instances, and colocation services provided by phoenixNAP to its enterprise and cloud customers.
Notable

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
