About this network

AS9085 (SUPERMEDIA-AS) is held by SUPERMEDIA Sp. z o.o., a Warsaw-based Polish telecom and business internet provider.

What it's used for

SUPERMEDIA operates as a connectivity and telecom provider. The AS announces roughly 42,000 IPv4 addresses across several blocks (notably 212.75.96.0/19 and 212.180.128.0/17) plus two IPv6 prefixes, with about 24 observed BGP neighbours. Sampled reverse DNS returns operator infrastructure names such as c1-fe0-0.sen.warszawa.supermedia.pl and millenium.warszawa.supermedia.pl, i.e. backbone/PoP routers in Warsaw rather than dynamic subscriber pools.

Notable

The main prefix has been announced since 2000, marking SUPERMEDIA as a long-standing Polish provider. The Warsaw-centric router naming and moderate peering point to a business/enterprise-focused ISP rather than a mass-market consumer eyeball network.

Interesting

The mix of a large legacy /17 alongside newer 185.x /22-/24 blocks reflects a provider that has accumulated addressing over two decades of operation.
