isp residential cable dsl

The AS handle ARPNET-AS is held by ARPNET WOJCIECH CHODACKI.

What it's used for

  • The address space carries residential and small-business internet access, evidenced by netnames PL-ARPNET and ARPNET-RUDASL-PL and reverse DNS entries like host91221122128.arpnet.pl.
  • The network announces 768 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 7 observed neighbours, indicating a local access provider rather than a transit hub.
  • Traffic consists of subscriber eyeballs for cable and DSL connections in the Ruda Śląska region of Poland.

Notable

  • Registrants align with the announcer, with ARPNET WOJCIECH CHODACKI listed for the primary block and ARPNET-RUDASL-PL for the secondary block.
  • The inventory is compact, consisting of two IPv4 prefixes and one IPv6 prefix, typical of a regional ISP.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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.
