What it's used for

• The space carries corporate infrastructure, evidenced by the netname DE-FQUADRAT and registrant f-quadrat IT GmbH.
• The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
• Traffic from this AS consists of internal corporate endpoints for the company's operations, as the reverse DNS entries follow a generic internal naming convention (ipv4.as218529.net) without specific customer or access technology identifiers.

Notable

• The company was established in 2022 as HeartESC GmbH and changed its name to f-quadrat IT GmbH in 2025.
• The address inventory is minimal, consisting of a single /24 block and a single /48 IPv6 prefix, consistent with a small-scale enterprise deployment.
