Summary

Enoch-Pratt Free Library

United States · AI-generated

education legacy

EPFL-AS is the Enoch Pratt Free Library, the public library system of Baltimore and Maryland's designated State Library Resource Center. Despite the handle, this is not EPFL in Lausanne; the ARIN registrant is the Baltimore library.

What it's used for

  • Sailor, the statewide data network established by Maryland's public libraries, which provides internet access and IT infrastructure to library systems across the state.
  • Roughly 82k IPv4 addresses, dominated by a 169.156.0.0/16 and a 64.26.64.0/18, sized for a statewide library network rather than a single building.

Notable

  • An institutional public-sector network address. The space serves library branches and the patrons using them, so it behaves like an education network rather than a residential ISP.
  • The technical contact on the ASN is registered as the Sailor network engineer, which is the clearest confirmation that this AS is the library-network backbone and not the library's office LAN.

Interesting

  • The handle is a genuine trap: EPFL reads instantly as École Polytechnique Fédérale de Lausanne, a Swiss university, and the AS is in fact a US public library. Registry handles reward being read carefully.

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 1,778 prefixes, as published 2026-10-20. 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.
