Any provider running and providing their own DNS Resolver?

SillyGoose

Hello everyone,

I have been working on a fast DNS caching service using XDP and eBPF to serve requests faster by caching and serving them at NIC level ensuring fastest responses.

I plan to open-source all the code but before I do, I would love to test it out. If any provider is willing to provide support by using the DNS as a default resolver on their servers and Able to provide servers to run the DNS service on is much appreciated.

The only requirement that this needs to be run is a XDP offload supported NIC. Possibly Meallnox.

This is just a fun/free project. I just do this in my free time nothing much.

Thanks!

No.

as I know the XDP TCP protection is based on Window Size Scaling,
UDP for rate limiting and nothing special!

maybe I am wrong
