cable isp residential poland

The AS handle RETSAT is operated by Stowarzyszenie Telewizji Kablowej 'Ret-Sat 1'.

What it's used for

  • The address space carries residential cable access traffic, evidenced by reverse DNS entries such as terminal-1-128.retsat1.com.pl and terminal-3-128.retsat1.com.pl.
  • The network announces 2048 IPv4 addresses across 3 prefixes and maintains 8 observed neighbours, a ratio consistent with an access provider rather than a transit carrier.

Notable

  • All three announced prefixes share the netname STK-Retsat1-PL and are registered to the same entity, Stowarzyszenie Telewizji Kablowej 'Ret-Sat 1', confirming a unified operational estate.
  • The inventory consists of three distinct IPv4 blocks: 193.238.92.0/22, 195.13.38.0/23, and 195.26.22.0/23, with no IPv6 prefixes in the inventory.

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: 442 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.
