Summary

Poland · AI-generated

residential isp poland wired

PROMONTEL-AS is operated by Promontel Sp. z o.o.

What it's used for

  • The address space carries residential customer endpoints, evidenced by reverse DNS entries such as cpe-91-193-14-254.promontel.net.pl and unassigned.promontel.net.pl.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio indicative of an access network providing last-mile connectivity.
  • Traffic from this AS consists of subscriber eyeballs for a wired telecommunications carrier operating in Poland.

Notable

  • Registrants align with the announcer for the primary prefix 91.193.12.0/22 (netname PROMONTEL-NET), while the secondary prefix 193.59.60.0/22 (netname PROMOKOZ) is registered to NASK LIR.
  • The address inventory is small and subdivided into two /22 blocks, consistent with a regional ISP managing a specific customer base.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
