residential isp poland

IT-NETWORKS-AS is operated by IT Networks Sp. z o.o.

What it's used for

  • The address space carries residential broadband traffic, evidenced by netnames IT-NETWORKS-V4 and IT-NETWORKS-PPPoE and reverse DNS entries for neter.pl and sky24.pl.
  • The AS announces 1,536 IPv4 addresses across 2 prefixes and maintains 5 observed neighbours, a ratio consistent with an access network serving end-user subscribers.
  • Traffic consists of subscriber eyeballs for the neter.pl and sky24.pl brands, which are Polish internet service providers.

Notable

  • Registrants for both prefixes align with the announcer, listing IT-Networks NOC and IT NETWORKS SP ZOO.
  • The inventory is composed of two distinct IPv4 blocks: 91.210.244.0/22 and 193.203.206.0/23.

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 1,781 prefixes, as published 2026-10-16. 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.
