Summary
Eurobank Bulgaria AD (Postbank)
enterprise finance legacy
PBPF-AS — the network of Eurobank Bulgaria AD, the Sofia-based bank that trades as Postbank and is part of the Greek Eurobank group.
What it's used for
- Corporate and banking infrastructure: branch connectivity, online and mobile banking, and the bank's public-facing services.
- A single /24 — enough for one institution's public footprint, not for reselling connectivity.
Notable
- Bank address space is institutional. Traffic from it is the bank's own systems and staff, never retail customers, so it should not be treated as consumer or hosting space.
- Banks typically run their own ASN so they can multi-home across carriers and keep their addresses portable, which matters when regulators expect continuity of payment services.
Interesting
- Postbank grew by absorbing other Bulgarian banks (DZI Bank in 2007, Piraeus Bank Bulgaria in 2019), which is how it reached the top tier of the Bulgarian market. The
PBPF-AShandle predates the current organisation name in the RIPE registry.

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 1,779 prefixes, as published 2026-10-23. 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.
