Summary

Hycom SA

Poland · AI-generated

business poland b2b software

The AS handle HYCOM is held by Hycom SA.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname PL-HYCOM-20151021 and reverse DNS entries like b255.rev.hycom.pl and c254.rev.hycom.pl.
  • The inventory consists of a single IPv4 prefix, 185.122.148.0/22, comprising 1024 addresses, with 0 IPv6 prefixes announced.
  • With only 2 observed neighbours, the network operates as a small, isolated business endpoint rather than a transit or access provider.
  • Traffic from this AS originates from Hycom SA, a Polish company based in Lodz that provides B2B self-service and eCommerce solutions, indicating the space supports web/API endpoints and office operations.

Notable

  • The RDAP registrant HYCOM SA matches the AS holder, confirming consistent ownership of the announced space.
  • The address inventory is a single contiguous /22 block, typical for a small corporate entity requiring a modest range of public IPs for its services.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
