About this network

GEMIUS-NETWORK is operated by Gemius SA.

What it's used for

• The address space carries internal infrastructure for Gemius, a Polish media analytics and digital measurement company, as indicated by netnames GEMIUS and Gemius-2 and reverse DNS entries like network1.gem.pl and ip-2-64.gem.pl.
• The AS announces 1280 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
• Traffic from this AS consists of office workers and web/API endpoints supporting Gemius's digital analytics services.

Notable

• Registrants for the largest prefixes are GEMIUS SA for 91.221.126.0/23 and ATMAN RIPE Administrators or ATMAN NOC for the 85.232.x.x and 213.189.48.0/24 blocks, suggesting some address space was historically allocated via ATMAN or is managed under their administrative umbrella.
• The inventory is finely subdivided into four distinct IPv4 prefixes, consistent with an internal corporate estate segmented by site or function.
