Summary

POAS

Finland · AI-generated

residential student housing finnish

POAS-AS is operated by Pirkan Opiskelija-asunnot Oy.

What it's used for

  • The address space carries dynamic residential traffic, evidenced by reverse DNS entries such as ip-40-0.dyn.poasnet.fi and netnames FI-OPINTANNER-20100423 and FI-OPINTANNER-20180104.
  • The network announces 9,216 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale access network rather than a transit provider.
  • Traffic consists of internet access for residents of student and young professional rental housing in Tampere, Finland.

Notable

  • Registrants for both announced prefixes are Opintanner Registry Management and Pirkan Opiskelija-asunnot Oy, aligning with the AS holder.
  • The address inventory is compact, consisting of a /19 and a /22 block, consistent with the scale of a single-city housing provider.

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
