What it's used for
- The address space carries university infrastructure, evidenced by reverse DNS entries such as
voices-student-net.wsisiz.edu.plandchronicles-console2.wsisiz.edu.pl. - The AS announces 1536 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 10 observed neighbours, a ratio consistent with an institutional access network.

Reputation
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
