history

Project history and usage

ICANN RDAP is ICANN's open-source implementation for the Registry Data Access Protocol, with command-line tools and Rust crates for RDAP clients, common data structures, and server work. 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.
