About this network

P4NET is operated by Play (P4 Sp. z o.o.), a major Polish telecommunications provider.

What it's used for

• The address space carries residential and mobile subscriber traffic, evidenced by reverse DNS entries such as user-31-174-128-0.play-internet.pl and user-static-164-126-128-0.mobile.play-internet.pl.
• The network announces 565,248 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, while maintaining 30 observed neighbours; this high address-to-neighbour ratio indicates an access/eyeball network rather than a transit provider.
• Traffic consists of consumer broadband (DSL/cable) and mobile data sessions for Play's subscriber base in Poland.

Notable

• Registrants for most prefixes are P4 Sp. z o.o. or P4 Team, consistent with the announcer; the 164.126.0.0/15 block is registered to Various Registries (Maintained by ARIN) with netname NET164.
• The inventory includes a mix of large /15 blocks and smaller /17 to /19 allocations, with netnames like PL-PROJECT4 and PLAYMBB reflecting different acquisition or service eras.
