DBNX files are associated with Netscape Navigator, the web browser developed by Netscape Communications. In the Macintosh version, the files contain data about hosts.
Netscape Navigator was also available for Microsoft Windows, but this record refers specifically to the host file used by the Mac version. The DBNX format is obsolete and is no longer in active use.
Open a DBNX file with the Macintosh version of Netscape Navigator that created it. Because the file is an internal host data file, it may not provide useful content when opened directly.
The Windows version of Netscape Navigator may be associated with this extension, but it is not necessarily compatible with the Mac host file.
DBNX files are internal Netscape Navigator data files. They normally should be used by the original Macintosh version of Netscape Navigator rather than converted.
