DNS queries in Java.

Here is some code from the vaults. I wrote this circa 1997 to support a Java-based email server that I wrote. I’m sure there are better/newer solutions available, but I hate to see code go to waste.

• DNSBrowse.java — A simple command-line client that uses the query classes.
• DNSService.java — The static class that supports setting server addresses and executing queries.
• DNSQuery.java — Wrapper class for encoding and decoding DNS query messages.
• DNSResourceRecord.java — Low-level class for decoding binary resource records into their components.

The source code is available for download as DNSQuery.zip.
