Summary

Secure-24

United States of America · AI-generated

hosting managed-services ntt

SECURE-24-AS is operated by NTT Managed Services Americas, LLC.

What it's used for

  • The address space carries managed services and data center infrastructure, evidenced by netnames such as SECURE-24-DCD-NETWORK, SECUR-26, and SECURE-24-DCE.
  • With 17,680 IPv4 addresses across 29 prefixes and only 6 observed neighbours, the AS functions as a hosting or managed services provider rather than a transit carrier.
  • Traffic from this AS consists of web/API endpoints, data center workloads, and managed service instances for enterprise clients.

Notable

  • Registrants largely align with the announcer, with NTT Managed Services Americas, LLC holding the majority of prefixes; exceptions include Cogent Communications, LLC for 38.101.80.0/22 and 38.103.80.0/22, and Renown Health for 204.115.220.0/22.
  • The address inventory is fragmented across multiple /22 and /23 blocks, reflecting a collection of acquired or leased ranges rather than a single contiguous allocation.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
