We have in use the different networks, the first address space belongs osanet network which is a part of CESNET network with address 195.113.113.128/27,
students must act very carefully with every device connected into
this network because of security. This network is in the front of
university firewall and the standard restricted rules are not applied
into this address space. This network is totally open therefore a
firewall should be installed into each connected device.
The second network uses ordinary address space of building N 158.196.81.0/24,
MAC of every device must be registered for assignment of IP address
from DHCP. The third network is ordinary a university wireless network,
WiFi access point is located in laboratory N211. The last network is 158.196.142.0/26
and serves as a experimental network, it is a part of university
network but without a obligation to register MAC address of device,
with own DHCP server, DNS and rules which are set by students.
