What both publish
| Fact | Masscan | NetsCLI |
|---|---|---|
| Integrations | The project describes PF_RING DNA support for high-speed packet transmission and says Masscan can use PF_RING ZC when the adapter name indicates it. | The MCP server runs over stdio and exposes structured tools for network discovery, scanning, ping, DNS, ARP, host inspection, sweeps, interfaces, and mDNS discovery. |
| Maker | The repository credits Robert David Graham as the creator and gives his contact email and @ErrataRob account. | The site credits Felix Stubner as the maker. |
| Platforms | Linux is the primary target; the code also runs on Windows and macOS, and the README gives build instructions for FreeBSD. | The CLI and terminal UI are published for Windows, macOS, and Linux; the desktop app is available for those systems as well. |
| Purpose | Masscan is an Internet-scale TCP port scanner designed for wide-range scanning of many machines. | NetsCLI is an open-source Rust network scanner for discovering LAN hosts, scanning TCP and UDP ports, querying DNS, and inspecting hosts. |
