The CZDS website provides sensitive information, and therefore requires a relatively modern browser capable of decrypting file transfer credentials and other sensitive information. This requirement is not absolute; should a Registry Operator choose to grant access to zone data using direct downloads instead of file transfers, then the links supplied on each Request will be supported by most any web browser.
If zone data is only available via file transfer, the following browsers have been tested and can successfully decrypt the information necessary to retrieve zone data. The version numbers listed are the minimum required. Unless otherwise noted any newer version is also compatible:
- Firefox 22
- Chrome 26
- Internet Explorer 9
- Safari 5.1 (use Apple Software Update inside Mac OS X)
- Opera 12
Each browser has been linked to its download page if applicable, allowing you to update your browser of choice. Alternatively, use the update features inside each browser.
