education university peerings

SILWEB-AS-PEERINGS is operated by Silesian University of Technology, Computer Centre.

What it's used for

  • The space carries university network traffic, identified by the netname SASK-PEERINGS and registrant PL-CKPOLSL Hostmaster Team.
  • The AS announces 256 IPv4 addresses within a single prefix (83.230.94.0/24) and has 0 IPv6 prefixes.
  • With only 1 observed neighbour, this AS functions as a small, isolated peering or transit point for the university's infrastructure rather than a large-scale access network.

Notable

  • The registrant PL-CKPOLSL Hostmaster Team aligns with the Silesian University of Technology (Politechnika Śląska) identity, confirming the ownership of the address space.
  • The address inventory consists of a single /24 block, indicating a compact and specific allocation for the university's computer centre operations.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, 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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
