Public Mirror DNSBL Server

- We are always in need of dedicated boxes at different locations to help us provide our services.

If you can provide a dedicated machine, please contact dns@nsZones.com.

Free mirror service is provided to sites who are willing to host a public mirror (serving data to other free users).

To host a public mirror we require:

Dedicated Intel PIII Server running Windows 2003
Minimum 1 GB Ram, 10GB HD, 1Mbit/sec bandwidth
Root access to the server with Terminal or VNC
Reliable network and power configuration.

If you are interested, please contact us.
We will configure and maintain it with the software needed to provide the nsZones blocklist service.

Please donate to the Project.

nsZones spends a lot of time and money keeping this project running and offers a first class service free of charge to you.

If you are satisfied with our service, and you want the blacklists stay free for all users, we would be glad to receive a small or a big donation from you.

All money donated to the project will be invested in new mirrors and increasing bandwidth so you will also benefit from better performance.

You can donate any amount you want with Paypal.

Smallest amounts can help to keep our blacklists free for all!
