In package-manager terms it is a modern successor-side tool for the domain registration lookup workflows historically associated with WHOIS. ### Project history The repository README says the software is written by the Internet Corporation for Assigned Names and Numbers for use with RDAP, an IETF-standard protocol whose extensions are handled in the IETF REGEXT working group. The legacy project wiki describes four Rust packages: `icann-rdap-cli`, `icann-rdap-client`, `icann-rdap-common`, and `icann-rdap-srv`. The project documentation moved from the GitHub wiki to a generated online user's manual. That migration reflects the tool's growth from repository notes into a documented CLI and library suite with installation, usage, and testing guidance. ### Adoption history The wiki documents distribution through Homebrew for the `rdap` and `rdap-test` commands, prebuilt release binaries for mainstream Linux, macOS, and Windows targets, and `cargo install icann-rdap-cli` for Rust users. Homebrew, Debian, MacPorts, Nix, and openSUSE package mappings in the input show packaging beyond the ICANN repository itself. ### How it is used The Homebrew formula installs the `rdap` client and `rdap-test` command. The intended use is querying RDAP services for domain and registry data, testing RDAP endpoints, and developing tooling around the ICANN-maintained Rust libraries. ### Why package nerds care This is notable because it packages a standards-body-adjacent network protocol client rather than a generic lookup script. It sits at the intersection of DNS operations, registrar data access, Rust CLI distribution, and the long transition from WHOIS-style text services to structured RDAP responses. ### Timeline - 2015: IETF published RDAP's core RFC series, establishing the protocol family that this tool implements. - 2020s: ICANN RDAP appears as a Rust workspace with CLI, client, common, and server crates. - 2020s: Documentation moved from the project wiki to the generated ICANN RDAP Users Manual. - 2020s: Tags from v0.0.1 through v0.0.29 record ongoing packaged releases. ### Related projects - Related work includes RDAP itself, the IETF REGEXT working group, ICANN's RDAP program, WHOIS tooling, and Rust crates used to build domain-registration data clients and tests. ### Sources - - - - - ## Security Notes No matching local secret-handling manifest was found for icann-rdap.
