Unclassified RIPE
Summary
Garanti BBVA
finance business enterprise
A bank's network, with three of its blocks registered on the same day in 2003.
What it's used for
- The network of a Turkish bank and its technology subsidiary. 6,656 addresses across nine IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.
Notable
- Every block carries a variation of
TR-GARANTIBBVABANK, some plain and some dated. 217.68.212.0/22,217.68.220.0/22and217.68.216.0/23all carry the date20030716.91.188.192.0/22is dated20181120.- The AS handle is
GARANTI-TECH. - One of eighteen sampled addresses returned a name:
usrgunpi06.garantiteknoloji.com.tr.
Interesting
- Three blocks registered on one day, then a fifteen-year gap before the next dated one. Banks do not grow their networks continuously; they run a project, request everything it needs at once, and then leave the allocation alone until the next project. The date field turns that rhythm into something you can read off the record.
- The netnames all say
BBVAwhile the routing archive dates the AS to 2000, long before that name applied to this bank. Unlike netnames, which are effectively frozen once created, these were rewritten, which means somebody went back and updated a decade of records by hand after the ownership change. - Two neighbours and 6,656 addresses is a network built for reliability rather than reach. The visible surface of a bank is intentionally small. The one reverse name belongs to the technology subsidiary's domain rather than the bank's, which is who actually runs the infrastructure.

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 2026-10-27, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
