About this network
ZIELMAN-EDU-AS (AS9103) belongs to the University of Zielona Góra (Uniwersytet Zielonogorski) in western Poland. ZielMAN is the university's metropolitan academic network.
What it's used for
The AS announces a single IPv4 /20 (212.109.128.0/20, ~4k addresses) plus one IPv6 prefix, with only a few observed neighbours: the compact footprint of a single campus/metropolitan academic network connected upstream to Poland's national research network (PIONIER). It carries university teaching, research and administrative traffic rather than commercial or subscriber traffic.
Notable
- Announced from this AS since at least 2000, consistent with an early Polish academic allocation.
- No PTRs were returned on the addresses sampled.
Interesting
The -EDU-AS and ZIELMAN (Zielona Góra Metropolitan Area Network) handle both point to the same academic operator; there is no famous-name collision here.
