The AS handle INTROLAN-INTERNET is held by Introlan Marzenna Barbara Bronakowska.

What it's used for

  • The address space carries residential or small business internet access, evidenced by reverse DNS entries such as 128.114.introlan.pl and 64.113.introlan.pl.
  • The network announces 768 IPv4 addresses across 2 prefixes and maintains 7 observed neighbours, a ratio consistent with a small local access provider rather than a transit carrier.
  • Traffic from this AS consists of subscriber internet access for the Lomza region in Poland.

Notable

  • Registrants for both announced prefixes match the AS holder, with netname INTROLAN-Internet and registrant INTROLAN Marzenna Barbara Bronakowska.
  • The address inventory is compact, consisting of a single /23 and a single /24 block within the 91.239.112.0/22 range.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
