Summary

I-BS.PL

Poland · AI-generated

business poland small

The AS handle IBS-AS is held by I-BS.PL Sp. z.o.o.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname PL-IBS and registrant I-BS.PL Sp. z.o.o.; WDM.PL CORE IP NETWORK ADMINISTRATORS.
  • The inventory consists of 512 IPv4 addresses in a single /23 prefix (91.207.148.0/23) with 0 IPv6 prefixes, and only 1 observed neighbour, indicating a small, self-contained business network rather than a transit or large access provider.
  • Traffic from this AS represents internal corporate operations for I-BS.PL, a Polish telecommunications and IT services company.

Notable

  • The RDAP registrant I-BS.PL Sp. z.o.o. matches the registry holder IBS-AS I-BS.PL Sp. z.o.o., confirming consistent ownership.
  • The address inventory is a single contiguous /23 block, typical of a small enterprise or regional ISP 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 1,851 prefixes, as published 2026-11-03. 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.
