What it's used for

• The address space carries residential broadband traffic, evidenced by reverse DNS entries such as lan-242.net.esn.at, brc-243.net.esn.at, and 193-186-245-254.greenstream.at.
• The AS announces 2048 IPv4 addresses within a single /21 prefix (193.186.240.0/21) and has one observed neighbour, indicating a local access network rather than a transit provider.
• As a subsidiary of the regional energy utility Energie Steiermark AG, the network serves subscriber eyeballs for internet access in the Styria region of Austria.

Notable

• The RDAP registrant for the announced prefix is listed as unknown with the netname RIPE-NCC-MANAGED-ADDRESS-BLOCK, which does not explicitly match the AS holder name in the registry data.
• The address inventory consists of a single contiguous /21 block, typical for a regional broadband deployment.
