Summary

ZETO-RZESZOW

Poland · AI-generated

isp regional poland cable

ZETO-RZESZOW is operated by ZETO-RZESZOW Sp. z o.o.

What it's used for

  • The address space carries regional broadband access traffic, evidenced by reverse DNS entries such as h459182254.nm.zetorzeszow.pl and mawo.rz.izeto.pl, and netnames PL-ZETO-RZESZOW-20190423 and ZETO-RZESZOW-NET.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and maintains 6 observed neighbours, a ratio consistent with a regional access provider rather than a transit carrier.
  • Traffic from this AS consists of subscriber eyeballs for cable and DSL services in the Rzeszów region of Poland.

Notable

  • Registrants for both announced prefixes are listed as ZETO-RZESZOW Sp. z o.o., matching the AS holder.
  • The address inventory consists of two /22 blocks, one in the 45.9.0.0/16 range and one in the 91.192.0.0/16 range, with no IPv6 prefixes announced.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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 1,784 prefixes, as published 2026-10-19. 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.
