I4-DLU (IPv4 DNS Lookup Utility) is a powerful and user-friendly command-line tool designed to perform IPv4 DNS lookups. It allows users to easily resolve domain names and URLs to their corresponding IPv4 addresses. The utility supports testing common domain suffixes and all possible suffixes available in its database, making it a versatile tool for network administrators, developers, and anyone interested in DNS resolution.
- Common Suffix Testing: Automatically tests common domain suffixes (e.g.,
.com,.org,.net) to find valid IPv4 addresses. - Full Suffix Testing: Tests all possible domain suffixes (in its database) to ensure thorough coverage.
- Acceleration Mode: Offers an accelerated mode to speed up the testing process, though users should be aware of potential ISP violations.
- User-Friendly Interface: Simple and intuitive command-line interface for easy use.
- Clear Output: Provides clear and concise output of resolved IPv4 addresses.
