Package com.dkfqs.tools.dns Description

A DNS resolver for IPv4 and IPv6 host names which supports to measure resolve times.

This com.dkfqs.tools.dns library contains an integrated and modified 'dnsjava' GITHUB clone
which was taken at 22 October 2019 from https://github.com/dnsjava and is included in
com.dkfqs.tools.jar.

The 'dnsjava' source code has been modified in such a way that no dependencies to any other
Java third-party-libraries exists:
- all "import lombok.extern.slf4j.Slf4j;" statements have been removed.
- all log.debug(..) statements have been removed.
- all log.error(..) statements have been replaced by throw new RuntimeException(..).

Furthermore, all 'dnsjava' Java classes at top level (outside any package) have been removed,
and all Java classes of the 'test' folder have been removed.

All other functionality of 'dnsjava' is fully available and untouched.

The modified 'dnsjava' library was compiled with Java version 8.

To use the modified 'dnsjava' library in your source you have to add the JAR file
com.dkfqs.tools.jar to the CLASSPATH and to import org.xbill.DNS.* as usual.
