Slookup streamlines parallel DNS lookups for easy accessibility.
If you're looking for a simple but powerful program for parallelized DNS lookups, slookup might just be the software for you. With its user-friendly interface, this program is perfect for log parsing scripts and one-liners. The slookup project can read names (A/MX/NS lookups) or addresses (in dotted-quad format for PTR) on stdin and write the results on stdout, with one record per line.
One of the standout features of slookup is its ability to run up to 128 parallel DNS lookup processes. This feature can significantly speed up lookups for a large number of records, although it can easily overload a slow DNS server.
One caveat to keep in mind is that the output is written in the order the DNS replies are received, which usually differs from the input order when parallel lookups are done. Nevertheless, the software has been tested on a variety of platforms including Solaris, RedHat Linux, Debian, and FreeBSD.
What's more, the latest release of slookup includes support for looking up NS records. Overall, this is a fast and reliable program that is perfect for anyone who needs to perform DNS lookups quickly and efficiently.
