How can I contribute to

If you are a service provider and you use GBUdb data then consider standing up a public DNS slave to help make GBUdb data delivery more robust and to accelerate your local requests. DNS servers like this are fed via IXFR and updated every 10 minutes.

Another great way to contribute to is to make a financial donation. Financial donations help make it possible for us to offer openly and provide additional resources for on-going development and support.

How much should I donate?
