Grupa Biznes Polska

Poland · AI-generated

business corporate poland

GBP-AS is operated by Grupa Biznes Polska - Wnorowski i wspolnicy sp.j.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname PL-GBP-20091116 and reverse DNS entries like rev64.gbp.pl and rev127.gbp.pl.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and web endpoints for a Polish company providing economic information, tender monitoring, and business data services.

Notable

  • The registrant Grupa Biznes Polska - Wnorowski i wspolnicy sp.j matches the AS holder and the netname registrant.
  • The address inventory is compact, consisting of a single /24 IPv4 block and a /48 IPv6 prefix, consistent with a single-site corporate deployment.

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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
