AS12774 PWN-ASN
Unclassified RIPE
Summary
Wydawnictwo Naukowe PWN
media education business
Two /24s from different ranges, held by a Polish academic publisher.
What it's used for
- Corporate networking for a scientific and educational publisher. 512 addresses in two IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.
Notable
- The inventory is
193.105.45.0/24and195.230.120.0/24. - Both carry the netname
PWN-NET-PL, registered to Wydawnictwo Naukowe PWN SA. - One sampled address answered, as
mc2.pwn.net.pl. - First observed in the routing archive in April 2008.
Interesting
- A publisher with its own AS number is a company that decided its internet presence was worth owning outright. Two
/24s from unrelated ranges, announced together under two upstreams, buys the ability to change provider without renumbering — which for an organisation whose services are cited by address in library systems and institutional allow-lists is worth more than the addresses themselves. - The two blocks share a netname but not a range, which means they were assigned at different times and filed under the same label. Netnames identify the holder's network, not the allocation, so they are the thread that ties otherwise unrelated space together.
mc2is a host name of the kind that only means something to the people who set it. Reverse DNS on a corporate network is written for operators, not for the public, and short cryptic names are the norm rather than the exception.

Interconnection
Peering at a glance
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 2026-10-20, 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: 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.
