zmap binary package in Ubuntu Focal riscv64

 ZMap is a network scanner that enables researchers to
 easily perform Internet-wide network studies. With a single
 machine and a well provisioned network uplink, ZMap is capable of
 performing a complete scan of the IPv4 address space in under 45
 minutes, approaching the theoretical limit of gigabit Ethernet.
 .
 ZMap can be used to study protocol adoption over time, monitor
 service availability, and help people better understand large systems
 distributed across the Internet.
