A simple command-line tool to query RDAP servers for IP address information. This is a Rust-based alternative to the traditional whois command, providing more structured information like organization, CIDR, and AS number.

• Look up IPv4 and IPv6 addresses.
• Choose from a list of well-known RDAP servers (RIRs).
• Use a custom RDAP server URL.
• Timeout configuration.
• Lists known RDAP servers.

• Rust (latest stable version recommended)

1. Clone the repository:

   git clone <repository-url>
   cd whois-rdap

2. Build the project:

   cargo build --release

   The executable will be in target/release/whois-rdap.

rdap-whois [OPTIONS] <IP>

• Look up an IP with the default RIR (RIPE):

  ./target/release/whois-rdap 8.8.8.8

• Look up an IP using a specific RIR:

  ./target/release/whois-rdap --rir arin 2606:4700:4700::1111

• Use a custom RDAP server:

  ./target/release/whois-rdap --server https://rdap.example.com/rdap 192.0.2.1

• List all known servers:

  ./target/release/whois-rdap --list-servers

• Print a successful lookup as a compact JSON string:

  ./target/release/whois-rdap --json 8.8.8.8

• <IP>: The IPv4 or IPv6 address to look up.
• --rir <RIR>: Pick a known RDAP server. (e.g., ripe, arin, apnic, lacnic, afrinic, iana)
• --server <URL>: Use a custom RDAP server base URL.
• --list-servers: List all known servers and exit.
• --json: Print successful lookup output as a compact JSON string.
• --timeout <SECONDS>: Request timeout in seconds (default: 15).
• -h, --help: Print help information.
• -V, --version: Print version information.
