AS12729 HSBC_TR_BANK_INTERNET
Unclassified RIPE
Summary
HSBC Turkey
finance enterprise
Every block still filed under the name of a bank that no longer exists.
What it's used for
- Corporate and internet banking networks in Turkey. 8,192 addresses in three IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.
Notable
- All three prefixes carry the netname
TR-DEMIRBANK-19991028, a name that is not the holder's. - The registrant on each is HSBC Bank Anonim Sirketi.
- The three blocks are contiguous:
212.127.96.0/21,212.127.104.0/21and212.127.112.0/20sit end to end. - Nine sampled addresses were queried and none returned a name.
Interesting
- October 1999 is the date on the registration, and the name on it belongs to the bank that filed it. What the record shows is that address space changed hands with the institution and nobody ever renamed it, so the registry still answers a question about ownership with an answer about history.
- Three contiguous blocks announced separately, adding to a single
/19-shaped range, is aggregation left undone. One announcement would carry the same traffic and cost every router two fewer entries; three is what you get when each piece was turned up at a different time and nothing forced a tidy-up. - The AS handle spells out
BANK_INTERNET, which is the network's job description. Retail banking has one externally reachable function, and naming the AS after it is honest in a way that most corporate handles are not.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
