An A record is a type of DNS record that maps a domain name to its corresponding IPv4 address. When you perform an nslookup using our A Record DNS Lookup tool, it queries DNS servers to retrieve the IP addresses associated with the specified domain. This helps you verify if your domain points to the correct server, which is essential for website accessibility.
If you enter a root domain like example.com, our tool will automatically check for A records for both example.com and www.example.com. This ensures that both the root domain and the 'www' subdomain are properly configured. For other subdomains, only the specified domain will be checked.
An A (Address) record links a domain name to its corresponding IPv4 address. It is a fundamental part of the DNS system, allowing users to access websites using domain names instead of IP addresses. Proper configuration of A records ensures that visitors can reach your website without issues.
Performing a DNS lookup and domain check using our tool helps you identify any misconfigurations or propagation delays. Regularly checking your A records can prevent downtime and connectivity problems.
