Summary
SGH Warsaw School of Economics
education university legacy
Szkoła Główna Handlowa w Warszawie (SGH-PL) — the SGH Warsaw School of Economics, Poland's oldest business and economics university, founded in 1906. The worklist handle's long tail, Centrum Technologii Informatycznych i Infrastruktury, is simply the university's IT and infrastructure centre, which runs the network.
What it's used for
- Campus networking for a single institution: one
194.145.96.0/20of about 4,000 addresses, registered as provider-independent space directly to the university, announced through a single upstream. - The rDNS that exists lands on
sgh.waw.pl— the university's own domain, and the address ofwww.sgh.waw.plitself sits inside this block. Most of the space carries no PTR at all, which is normal for a campus that NATs its internal networks.
Notable
- Institutional address space, not consumer or hosting space: staff, students, research and the university's public web and mail services. There are no dynamic, PPPoE or subscriber-pool naming conventions anywhere in it.
- The single upstream is the standard shape for a Polish university connected to PIONIER, the national research and education network, which aggregates academic institutions rather than having each buy commercial transit.
Interesting
- SGH is a business school rather than a technical one, which makes an own-AS-and-own-prefix setup a little unusual; most of the early European academic allocations went to engineering and science faculties first.

Classification and threat
Education University, school or national research and education network.
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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
