Summary
TASK (Gdańsk Academic Computer Centre)
education research hosting
A university computing centre with 29 neighbours, carrying regional businesses on its own blocks.
What it's used for
- The academic computer centre of a Polish technical university, serving the region's research institutions. 27,648 addresses across twelve IPv4 prefixes, one IPv6 prefix, and 29 observed BGP neighbours.
Notable
- The largest blocks are
89.191.160.0/19and213.192.64.0/19, with213.192.96.0/20and213.192.120.0/21alongside. - Three prefixes share the netname
PL-TASK-20001024, registered to the technical university;89.191.160.0/19isPL-TASK-20060620. - Two blocks belong to other organisations:
178.217.248.0/21isPRO-SYSTEM, and91.244.248.0/22isPCPD2-NET, a regional data-processing centre. - One of eighteen sampled addresses returned a name:
573eede3bb107.rev.snt.net.pl.
Interesting
- The one reverse name that answered is a hexadecimal string. Generated reverse zones usually encode the address in the hostname so an operator can read it; hashing it instead produces a unique name that tells you nothing, which is either a privacy choice or the shortest path to guaranteeing uniqueness.
- Three blocks stamped the same October 2000 date is one allocation recorded as three objects. The registry's dates record filing days, so identical dates across prefixes mark a single transaction rather than a pattern of growth.
- A university centre announcing a commercial systems house and a regional data centre is what academic networking looks like in practice. The research network was the only serious connectivity in the region for years, so it took on neighbours that were never academic, and the arrangement outlasted the reason for it.

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.
Transit providers
2 upstream, 27 downstream and 34 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, 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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
