Arm Whois

⁠Arm Whois is a legacy network utility software designed for Windows that automates the process of looking up domain ownership and IP address registration data. Created by Armcode, it acts as a desktop client for the global WHOIS protocol, allowing network administrators and cybersecurity professionals to trace host information, location data, and domain records without using web-based search tools. What Does Arm Whois Do?

The software queries distributed databases managed by registrars and registries around the world to compile a complete profile of an internet resource. Key features include:

Intelligent Routing: Unlike standard command-line tools, it automatically determines which country database or registry is authoritative for a given IP address or hostname and forwards the request there.

Domain Ownership Details: It reveals who registered a domain, the registrar used, creation/expiration dates, and technical contact information.

IP Address Block Tracking: It allows users to input an IP address to find the corresponding network provider, country, state, and specific location mapping. Standard Information Revealed in a Lookup

When utilizing a tool like Arm Whois, a complete domain lookup typically returns several distinct blocks of metadata: Data Category Information Provided Registrar Info

The company where the domain was purchased (e.g., Namecheap, GoDaddy) and their contact details. Important Dates

Exact timestamps for when the domain was first registered, last updated, and when it will expire. Registrant Details

The owner’s name, physical address, email, and phone number (unless redacted by privacy protocols). Network Infrastructure

Designated nameservers pointing to where the website is hosted, alongside domain status codes. Important Security Warning Regarding Arm Whois

If you are looking to download the standalone Arm Whois (specifically version 3.11) utility, you should exercise extreme caution. Cybersecurity databases flag this legacy application for severe security vulnerabilities, including critical stack-based buffer overflows (such as ⁠CVE-2018-25427 and ⁠CVE-2018-25432).

An attacker can input a malformed domain or IP address string exceeding specific byte limits into the application, causing it to crash or potentially execute malicious code to compromise your local system. Whois IP Search & Whois Domain Lookup
