About this network

AS197637 is operated by ropa GmbH.

What it's used for

• The address space carries municipal broadband infrastructure, evidenced by netnames like DE-ROPANET and DE-ROPA-L1, and reverse DNS entries such as static.isp.ropa.net and server1-b.ropa-net.de.
• With 32,256 IPv4 addresses announced across 27 prefixes and 101 observed neighbours, the high neighbour-to-address ratio indicates a transit or carrier-grade role rather than a pure access network.
• ropa GmbH provides telecommunications services specifically designed to support city utilities (Stadtwerke) in managing sustainable and efficient municipal broadband supply.

Notable

• Registrants for the majority of prefixes are ropa GmbH or ropa NOC, while several blocks including 31.220.64.0/21 and 159.48.32.0/22 are registered to TerraTransit AG, suggesting leased or historically acquired space.
• The inventory consists of a mix of /21, /22, and /23 blocks, with the largest allocations being /21s, indicating a segmented corporate estate rather than a single contiguous allocation.
