# Domain to IPv4 Converter in C
This project provides a simple command-line tool written in C to convert domain names to their corresponding IPv4 addresses. It uses the getaddrinfo function from the netdb.h library to perform DNS resolution and retrieve IP addresses associated with a given domain name.
## Usage
Simply compile the provided source code and run the executable with the domain name as an argument.
```bash
$ gcc domain_to_ipv4.c -o domain_to_ipv4
```
```bash
$ ./domain_to_ipv4
Usage: ./domain_to_ipv4
```
```bash
$ ./domain_to_ipv4 example.com
93.184.216.34
```
