residential isp cable dsl

P4NET_POZ is operated by Play (P4 Sp. z o.o.).

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries such as user-188-33-64-0.play-internet.pl and 185-89-185-0.dynamic.play.pl.
  • The network announces 74,752 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining only 7 observed neighbours, a ratio characteristic of an access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for Play's cable and DSL services in Poland.

Notable

  • Registrants for all major prefixes are consistent with the announcer, listing P4 Sp. z o.o. and P4 Team.
  • The inventory includes the netname PLAY_MBB for the 5.173.224.0/19 block, reflecting the operator's rebranding from P4 to Play.
  • The address inventory is composed of three distinct IPv4 blocks, including a /16 and a /19, alongside a single /32 IPv6 prefix.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
