Slookup streamlines parallel DNS lookups for easy accessibility.
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.
