🤖 Ai回答: Whois ARIN typically refers to querying the American Registry for Internet Numbers (ARIN) database using the WHOIS protocol to retrieve information about IP address blocks, autonomous system numbers (ASNs), and related resources.
What is ARIN?
ARIN is one of the five Regional Internet Registries (RIRs) responsible for managing and distributing Internet number resources (IP addresses and ASNs) in North America, parts of the Caribbean, and sub-Saharan Africa.
What does Whois ARIN mean?
When someone says Whois ARIN, they usually mean:
1、Querying ARIN's WHOIS database to find information about IP address allocations.
2、Using ARIN's official WHOIS service to look up details like:
Owner of an IP address block
Contact information (registrant, technical, administrative contacts)
Registration date and expiration
Network description
How to Use Whois ARIN
1、Online WHOIS Lookup
Visit ARIN's official WHOIS service:
👉 [https://whois.arin.net](https://whois.arin.net)
Example:
Enter an IP address like `8.8.8.8` → You'll get info about Google's public DNS server.
Enter an ASN like `AS15169` → You'll get details about Google's network.
2、Command Line (using `whois` tool)
bash
whois 8.8.8.8
This will return ARIN WHOIS data if the IP is registered through ARIN.
3、ARIN's REST API
For developers, ARIN provides a RESTful API:
👉 [https://www.arin.net/resources/whois/api/](https://www.arin.net/resources/whois/api/)
Example API call:
bash
curl -s https://whois.arin.net/rest/ip/8.8.8.8 | jq

Key Points:
ARIN WHOIS data is publicly available.
It includes technical and administrative contact details.
It helps in network troubleshooting, security investigations, and IP ownership verification.
Note:
ARIN transitioned to a whois service that is now queryable via REST API and web interface, and the traditional WHOIS port (43) is no longer supported for ARIN.
If you're asking about a specific IP or ASN, let me know and I can help look it up!
