About this network

SYNLINQ is operated by SYNLINQ, a German hosting and network services provider.

What it's used for

• The address space carries hosting infrastructure, evidenced by netnames such as DE-LIVING-BOTS and DE-MOS-IPS, and reverse DNS entries like famesystems.de, rdns.1nic.de, and mc-host24.de.
• With 30,464 IPv4 addresses and 125 observed neighbours, the ratio indicates a hosting or transit provider role rather than a large residential access network.
• Traffic from this AS consists of web servers, API endpoints, and hosted client applications, consistent with SYNLINQ's business as a hosting and network operator.

Notable

• Registrants include Mo's Operations GmbH, 1nic GmbH, Sascha Gericke trading as Gericke KG, Rene Roeth trading as ROETH & BECK GbR, intercolo GmbH, and Cogent Communications, LLC, alongside the primary holder Oliver Horscht trading as SYNLINQ.
• The inventory includes a Cogent Communications prefix (COGENT-154-43-16), suggesting leased or historical address space.
• The address inventory is finely subdivided into numerous /22 and /23 blocks, typical of a hosting provider managing multiple customer or service segments.
