residential isp cable dsl

INTERNETIA_ETTH2-AS is operated by Netia SA.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS records pointing to internetia.net.pl and netnames such as PL-NETIA-20061117 and NETIA_NET2.
  • The AS announces 43,008 IPv4 addresses across 5 prefixes and 6 IPv6 prefixes, while maintaining only 1 observed neighbour, a ratio characteristic of an access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for cable and DSL customers in Poland, consistent with the operator's role as a regional ISP.

Notable

  • Registrants for the majority of prefixes are listed as Netia Telekom S.A. Contact Role or Netia SA, aligning with the current holder, though one prefix (78.31.166.0/23) is registered to FIBERNET Lukasz Wisniewski.
  • Netia SA is the successor entity to Netia Telekom S.A., reflecting corporate restructuring within the Netia group.
  • The inventory includes a mix of large blocks like 90.156.0.0/17 and smaller allocations, with one prefix registered under a different netname (FIBERNET).

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
