If you manage Domain Name System (DNS) records, you probably already know how seemingly minor errors can cause big problems. Leaving a semicolon off the end of a statement, forgetting the trailing period, or failing to add that right bracket can cause a DNS server to fail to load or to respond incorrectly to requests. Dlint is a utility that will check your domains for common errors, allowing you to fix them before a problem gets out of hand. Dlint uses Domain Information Groper (DiG) and a combination shell/Perl script to gather and parse DNS information. This script can help verify your configuration and save you some troubleshooting time in the future.
