K-net

K-net is a French provider of internet services, with its headquarters located in France. As an ISP, it delivers connectivity solutions to customers, which includes the operation of DNS infrastructure that supports domain name resolution for its users. The company’s core offerings revolve around providing reliable network access and associated telecommunications functions within its service area. Being based in France situates K-net within the European telecommunications market, where it operates alongside other regional and national carriers. Its role as a service provider implies responsibility for maintaining the availability and performance of the networks it manages. The firm’s operational focus includes ensuring that its infrastructure can handle typical traffic loads and resist disruptions.

On 28 August 2020, K-net was among several European ISPs targeted by a coordinated wave of DDoS attacks that employed DNS amplification and LDAP‑type techniques, peaking at approximately 300 Gbit/s. The assault specifically impacted K-net’s DNS infrastructure, causing service disruption that was mitigated within a single day. This incident occurred alongside reports of DDoS extortion demands involving Bitcoin, although investigators found no direct link between the attacks and those demands. The same timeframe saw a separate outage at CenturyLink, which was attributed to a misconfigured Flowspec rule implemented during DDoS mitigation efforts. K-net’s experience highlights the vulnerability of DNS services to large‑scale reflection attacks and the importance of rapid response capabilities. The event contributed to broader awareness of DDoS threats facing ISPs across Belgium, France, and the Netherlands. No further details about K-net’s size, ownership, or subsidiary relationships are provided in the available sources.
