Summary

Kolporter

Poland · AI-generated

isp residential poland fixed

KOLPORTER-AS is operated by Infover Sp. z o.o.

What it's used for

  • The address space carries fixed-line residential and business internet access, as indicated by the kolporter.com.pl reverse DNS domain and the KOLPORTER-NET netname.
  • The AS announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 4 observed routing neighbours, a ratio consistent with an access network providing last-mile connectivity.
  • Traffic from this AS consists of subscriber eyeballs and business users accessing the internet via Kolporter's fixed-line infrastructure in Poland.

Notable

  • Registrants for both announced prefixes are listed as Kolporter NOC; Infover Sp. z o.o., matching the AS holder.
  • The address inventory is compact, consisting of one /21 and one /22 block, typical for a regional Polish ISP.

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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
