PHP WHOIS client implementation. Sends the queries directly to the WHOIS services.

> **Project Origin**: This project is a maintained fork of [io-developer/php-whois](https://github.com/io-developer/php-whois). This version (`1.0.0`) is based on the original version `4.1.10`.

⚠️ Important: Rate Limiting & IP Blocking
---------------------------------------------

[](#️-important-rate-limiting--ip-blocking)

WHOIS servers often implement strict rate limiting policies. Sending too many queries in a short period of time may result in your IP address being temporarily or permanently blocked by the WHOIS server.

It is strongly recommended to:

- Implement a caching layer (see [Response caching](#response-caching)).
- Avoid bulk lookups without significant delays between requests.
- Respect the terms of service of each registry.
