Quick Answer
^(?:https?://)?(?:[^@\n]+@)?([^:/\n?]+)

Need to pull out the domain or full hostname from a list of URLs? This powerful regex pattern is designed to precisely capture the main domain (e.g., example.com, sub.domain.co.uk) from various URL formats. It efficiently handles common prefixes like http://, https://, and user credentials, ensuring you get the clean hostname without path, query, or fragment.

To use this, apply the regex in your preferred programming language (Python, JavaScript, PHP, Ruby, etc.) or text editor (VS Code, Sublime Text, Notepad++). The desired hostname will be captured in the first capturing group: ([^:/\n?]+). This pattern is invaluable for data extraction, analytics, and URL cleanup tasks, providing the immediate solution for your domain parsing needs.
