Summary

Prószyński Media

Poland · AI-generated

media business enterprise

A publishing house on a single /24, with underscores where every neighbour uses hyphens.

What it's used for

  • The network of a Polish book and magazine publisher. 256 addresses in one IPv4 prefix, two observed BGP neighbours, and no IPv6 announced.

Notable

  • The whole inventory is 193.218.115.0/24, netname PROSZYNSKI_MEDIA_NETWORK.
  • The AS handle is PROSZYNSKI_MEDIA_AS, also underscored.
  • First observed in the routing archive in August 2000.
  • Three addresses were sampled and none returned a name.

Interesting

  • Underscores in both the handle and the netname, where nearly every other record in this range uses hyphens. Underscores are not valid in hostnames, which is why the hyphen convention exists at all, but registry name fields have no such restriction and so the habit survives wherever someone brought it from another system.
  • A publisher with its own AS number is holding a routing identifier for a network of 256 addresses. In 2000 that was how a company with two upstream connections stayed reachable if one failed, and the arrangement has simply persisted; nothing about publishing requires it.
  • The diacritic in the company's name is stripped in every field of the record. Registry systems of this era were built for a restricted character set, and national alphabets were flattened on entry. The company still spells itself correctly everywhere except in the infrastructure that routes to it.
  • Nothing answers reverse lookups, and with 256 addresses and two neighbours there is very little here beyond an office.

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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
