Summary

BT Radianz

United States of America · AI-generated

hosting colocation business

RADIANZ-NUTLEY is operated by BT Americas, Inc, specifically its Radianz hosting division.

What it's used for

  • The address space carries colocation and hosting infrastructure, evidenced by netnames such as BRHO-NUTL-2006, PNAP-NYM-RADIAN-RM-01, and INAP-NYC-RADIANZH-20157.
  • With 7936 IPv4 addresses across 13 prefixes and only 5 observed neighbours, the ratio indicates a hosting or colocation provider rather than a transit or access network.

Notable

  • Registrants are consistent with the announcer, including RADIANZ Americas, Inc.; BT Radianz Hosting Operations, Radianz, Inc., and BT Americas, Inc.
  • The inventory includes a prefix registered to CEVA LOGISTICS U.S., INC. (136.143.139.0/24) and one to Seqirus Inc (23.249.8.0/22), suggesting leased or transferred space within the AS.
  • The address inventory is finely subdivided into 13 prefixes, reflecting site-by-site segmentation typical of a large corporate hosting estate.

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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
