Summary
P4 (Play)
isp mobile legacy
P4 Sp. z o.o. is the operator of Play, Poland's largest mobile network, which has also absorbed the former UPC Polska fixed-broadband business.
What it's used for
A large national eyeball network. The AS announces ~76 IPv4 prefixes (~1.6M addresses) plus IPv6. Sampled reverse DNS is overwhelmingly subscriber-facing: 193-47-160-1.dynamic.play.pl dynamic pools, 81-18-200-1.static.play.pl static assignments, and backbone router naming under as9141.pl (pl-waw26c-rr11_ae2.0.as9141.pl). This is retail mobile and fixed broadband address space.
Notable
- Play (P4) is the mobile brand; the handle "P4 Play UPC PL network" reflects the merger of Play with UPC Poland's cable/fibre network, so this AS now carries both mobile and fixed subscribers.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Mobile Cellular carrier. Addresses are shared by many handsets via CGNAT.
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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
