Summary

SENDnet

Poland · AI-generated

isp residential poland small

The AS handle SENDNET-AS is held by SENDnet Grzegorz Dacka.

What it's used for

  • The address space carries residential or small business internet access, evidenced by the netname SENDnet and reverse DNS entries pointing to non-registered.sendnet.pl.
  • The network announces 256 IPv4 addresses within a single /24 prefix (193.105.110.0/24) and maintains 1 observed neighbour, a ratio consistent with a small access provider rather than a transit carrier.
  • Traffic from this AS consists of end-user internet access for subscribers in Poland.

Notable

  • The RDAP registrant SENDnet Grzegorz Dacka matches the AS holder and netname, confirming consistent ownership.
  • The inventory is compact, consisting of a single contiguous /24 block with no announced IPv6 prefixes.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-21, 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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
