Hello there,
You can ascertain a website's domain age through various means:

WHOIS Lookup: Visit WHOIS websites and enter the domain name to find its creation or registration date.

Domain Age Checker Tools: Utilize online tools by inputting the URL to obtain the domain's age.

Internet Archive (Wayback Machine): View historical website snapshots on the Wayback Machine to identify the domain's age by its first snapshot date.

Domain Registrar: Check the domain registrar's website to see the registration date.

Employing any of these methods aids in assessing a domain's age and its trustworthiness.

The decision to keep your existing site or start a new, including "8171" depends on various factors, including your current site's performance, goals, and required improvements. Evaluate these factors before making a choice.
