Summary

PSJ sp. z o.o.

Poland · AI-generated

business poland small

PL-PSJ-ISP is held by PSJ sp. z o.o.

What it's used for

  • The space carries a single IPv4 block, 185.226.248.0/22, with netname PL-PSJ-20171019 and registrant PSJ sp. z o.o.
  • The AS announces 1024 IPv4 addresses across 1 prefix and maintains 1 observed neighbour, indicating a small, self-contained network rather than a transit or large access provider.
  • PSJ sp. z o.o. is a Polish enterprise operating in the seafood product preparation and packaging sector, suggesting the address space supports internal corporate operations rather than public internet service.

Notable

  • The RDAP registrant PSJ sp. z o.o. matches the AS holder, confirming consistent ownership.
  • The address inventory consists of a single contiguous /22 block, typical of a small business allocation.

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.
