DDoS on IPv64.net

18.05.2025 Update We were able to contain the DDoS with appropriately well-regulated firewall rules. We learned a lot ourselves and recorded everything that happened in a YouTube video. The services are available again as usual.

13.05.2025 Update After 3 days of silence, a DDoS occurred again today. All the LOG files collected have already been sent to the NRW police for investigation. We hope for the best. The IPv64 system is running very stable so far, even if an attack occurs. The stored data stays safe.

09.05.2025 Update - The attackers are apparently too dumb to run the DDoS on IPv6. IPv6 works without any problems. The attack is still running on IPv4. Connections on IPv4 are currently filtered and mostly completely blocked by IPv64.

08.05.2025 - We are currently struggling with a massive DDoS. We and the data center operator are working on a solution to stabilize the services again.
To put it bluntly - someone is targeting us very badly.

What is IPv64.net?

IPv64 is of course not a new Internet Protocol (64), but simply a deduplicated short form of IPv6 and IPv4. On the IPv64 site you will find a Dynamic DNS service (DynDNS) and many other useful tools for your daily internet experience.

With the dynamic DNS service of IPv64 you can register and use free subdomains. The update of the domain is done automatically by your own router or alternative hardware / software. Besides updating IP addresses, simple Let's Encrypt DNS challenges are also possible.

Own domains can be added and benefit from all IPv64.net features like DynDNS services, GEO load balancing, DDoS protection, DynDNS2 and SSL encryption.
