hosting colo

Three blocks registered to a carrier, announced by a research company, with a colo host in the reverse tree.

What it's used for

  • Hosting and colocation. 1,024 addresses in three IPv4 prefixes with two observed BGP neighbours and no IPv6 announced.

Notable

  • All three blocks are registered to NTT America, Inc., with a second contact reading VIPAR on each.
  • The netnames follow the carrier's scheme rather than the customer's: NTTA-205-238 on two blocks and NTTA-204-200 on the third.
  • NTTA-204-200 labels 204.203.92.0/24, so the number in the name does not match the block it is on.
  • The one address that answered reads amc-colo4.wiley.scnresearch.com.

Interesting

  • A netname built from the first two octets stops being accurate the moment the same name gets reused on space from elsewhere, and that has happened here. The label describes where the carrier's numbering started, not where this /24 sits.
  • amc-colo4.wiley is a customer's naming convention showing through the carrier's: a numbered colocation host under what reads as a site or client name. Two organisations' bookkeeping meeting on the same address, one in the registry and one in DNS.
  • Announcing provider-registered space with your own AS number is the ordinary arrangement for a colocation tenant who wants routing independence without applying for addresses.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-08, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
