Summary

PCC IT S.A.

Poland · AI-generated

business it telecom poland

The AS handle PCT-AS is held by PCC IT S.A., a Polish IT and telecommunications outsourcing provider.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by reverse DNS entries like pct064.pct.pl and pct127.pct.pl pointing to the pct.pl domain.
  • The network announces a single IPv4 prefix, 194.213.1.0/24, comprising 256 addresses, with 2 observed routing neighbours, indicating a small, self-contained business network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant PCC IT S.A. matches the AS holder, confirming consistent ownership of the PCT netname.
  • PCC IT S.A. is a subsidiary of PCC SE, a major Polish industrial group, operating in the computer systems design and telecommunications sector.
  • The inventory consists of a single /24 block with no announced IPv6 prefixes, reflecting a minimal footprint typical of a specific corporate site or internal service.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
