If you are unable to connect to a website despite having a working internet connection, which of the following is most likely the reason?

Correct option is A

A DNS (Domain Name System) server translates domain names (like www.example.com) into IP addresses. If the DNS server is down or misconfigured, your browser cannot resolve the domain name into its corresponding IP address, resulting in an inability to connect to the website, even with a working internet connection. This is a common issue that can be fixed by changing the DNS settings or waiting for the server to recover.
Important Key Points:
1. DNS Server Role: The DNS server plays a critical role in resolving domain names into IP addresses for website access.
2. Common Issue: DNS misconfiguration or downtime is one of the most frequent causes of website access issues despite a working connection.
3. Troubleshooting: Switching to a public DNS (like Google's 8.8.8.8) can often resolve this issue.
Knowledge Booster:
· Changed IP Address: Websites with updated IP addresses may take time to propagate DNS changes but are less likely to cause immediate connection issues.
· Browser Cache: A full or outdated cache can cause display issues but typically does not block website access.
· Firewall Settings: Incorrect firewall configurations might block specific sites but do not generally impact overall browsing if the internet is working.
· Outdated Operating System: An outdated OS rarely affects website connectivity directly, though it may cause other performance issues.
