ZDNS is a command-line utility that provides high-speed DNS lookups. ZDNS is written in Go and contains its own recursive resolution code and a cache optimized for performing lookups of a diverse set of names. We use https://github.com/zmap/dns to construct and parse raw DNS packets. For more information about ZDNS's architecture and performance, check out the following paper appearing at ACM's Internet Measurement Conference '22: https://lizizhikevich.github.io/assets/papers/ZDNS.pdf
