isp residential poland small

MARLENA is operated by Marlena Marek Zieba, a telecommunications service provider based in Konstantynów Łódzki, Poland.

What it's used for

  • The address space carries residential and small business internet access, evidenced by the 4web.pl reverse DNS entries and the netnames MARLENA and MarlenaNet.
  • With 1792 IPv4 addresses announced across 3 prefixes and only 2 observed routing neighbours, the network functions as a local access provider rather than a transit hub.
  • Traffic consists of subscriber eyeballs for internet access services provided in the Łódź region.

Notable

  • Registrants for the two largest prefixes (MARLENA and MarlenaNet) align with the AS holder, while the smallest prefix (91.216.99.0/24) is registered to VITAL P.P.H.U Witold Gaszewski under the netname VITAL.
  • The inventory is composed of three distinct IPv4 blocks with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,784 prefixes, as published 2026-10-19. 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.
