One record per line. It can run up to 128 parallel DNS lookup processes (easily overloading a slow DNS server) which makes for Really Fast lookups for a large number of records.Beware, output is written in the order the DNS replies are received, which is usually different from the input order if parallel lookups are done.It has been tested on the following platforms:Solaris 2.6 / UltraSparc / gcc 2.7.2.3RedHat Linux 7.0 / 2.2.17 / glibc-2.1.94 / gcc 2.96Debian sarge / 2.6.8.1 / glibc-2.3.2 / gcc 3.3.5 Debian etch / 2.6.15 / glibc-2.3.6 / gcc 4.0.3 FreeBSD 5.3-RELEASE / gcc 3.4.2 FreeBSD 6.0-RELEASE / gcc 3.4.4What's New in This Release:· Support for looking up NS records was added.
