DTCC-PTC-NETBLOCKandDTCC-207registered to the Depository Trust & Clearing Corporation. - The AS announces 6,144 IPv4 addresses across 7 prefixes and maintains 12 observed neighbours, a ratio consistent with a business network rather than a transit or access provider.
- Traffic from this AS consists of internal systems supporting DTCC's role as a post-trade market infrastructure provider, handling clearing, settlement, and trade processing for the global financial system.
Notable
- All registrants in the RDAP data agree with the announcer, consistently listing the Depository Trust & Clearing Corporation.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
12 upstream, 0 downstream and 12 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 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.
