Description:
Checks dns zone information using nameserver lookups
This program analyzes any DNS zone you specify, and reports any problems it finds by displaying errors and warnings. Then it descends recursively to examine all zones below the given one (this can be disabled with a command- line option). . You don't have to feed any BIND conffiles to Dlint. Dlint uses nameserver calls to gather information. . Designed for Unix, dlint is written in Bourne Shell and Perl.
