Summary
Toronto-Dominion Bank
enterprise legacy
Autonomous System 7734 (TDBANK) belongs to the Toronto-Dominion Bank (TD), one of Canada's largest banks and the parent of TD Canada Trust and the US retail arm TD Bank, N.A.
What it's used for
- Carrying TD's own corporate and banking infrastructure: internal enterprise networks, branch and office connectivity, public-facing online and mobile banking front ends, and the datacentre systems behind them.
- Announcing
142.205.0.0/16— a legacy Class B registered to Toronto-Dominion Bank in 1992 — sliced into a large number of longer prefixes, plus a handful of small blocks from other ranges.
Notable
- This is an enterprise network. Nothing here is sold as connectivity: an address in this space is a TD site, a TD server or a TD security appliance, not a customer of an ISP and not a hosting tenant.
- Reverse DNS is almost entirely absent across the
/16, which is typical of a bank: publishing a map of your internal estate in public DNS is an unnecessary disclosure, so financial institutions routinely leave the space dark. - The unusually fine-grained prefix breakdown (dozens of
/23s and/24s carved out of one Class B) is a fingerprint of a large, long-lived corporate network that has been re-segmented many times as the bank grew and merged.
Interesting
- Banks were among the earliest non-academic organisations to take large legacy allocations, and a 1992 Class B still being announced under its original holder's name is now a fairly rare thing.

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 2026-10-15, 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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
