Summary

Tullett Prebon

Singapore · AI-generated

finance business corporate

The AS handle TULLETTPREBON-AS-SG-AP is held by Tullett Prebon Singapore Limited.

What it's used for

  • The address space carries corporate network infrastructure, evidenced by netnames TULLETTPREBON and PREBON-AMS associated with registrants Tullett Prebon Singapore Limited and TP ICAP GROUP SERVICES LIMITED.
  • The inventory consists of 1024 IPv4 addresses across 3 prefixes, with 2 observed routing neighbours, indicating a small, internally managed corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and internal systems for the financial services firm, supporting its business operations in Singapore and Amsterdam.

Notable

  • Registrants align with the announcer, with Tullett Prebon Singapore Limited holding the majority of prefixes and TP ICAP GROUP SERVICES LIMITED holding the Amsterdam-based prefix.
  • The address inventory is finely subdivided into three distinct prefixes, reflecting site-by-site segmentation for a global financial institution.

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 1,783 prefixes, as published 2026-10-17. 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.
