Understanding the different types of DNS records and their functions
A records map a domain name to the IP address (IPv4) of the computer hosting the domain. They are the most fundamental type of DNS records.
Mail Exchange (MX) records specify the mail servers responsible for accepting email messages on behalf of a domain name. They include a priority value.
Name Server (NS) records delegate a domain or subdomain to a set of DNS servers. They specify which DNS servers are authoritative for a domain.
TXT records contain text information for sources outside your domain. They're often used for domain verification and email security (SPF, DKIM, DMARC).
The Domain Name System (DNS) is a fundamental component of the internet infrastructure, acting as the phonebook of the internet. It translates human-readable domain names into machine-readable IP addresses.
DNS settings can indirectly affect your website's SEO performance in several ways:
Fast DNS resolution contributes to quicker page loading times, which is a known ranking factor.
DNS issues can cause downtime, which can negatively impact search engine rankings.
Proper DNS configuration is required for SSL certificates, which are essential for SEO.
When changing domains, proper DNS setup ensures a smooth transition and preserves SEO value.
Use our DNS lookup tool regularly to ensure your DNS records are correctly configured and functioning properly.
Identifying and fixing DNS problems quickly
When you make changes to your DNS records, it can take time (typically 24-48 hours) for these changes to propagate across all DNS servers worldwide.
If your website is not accessible, it could be due to DNS configuration issues:
Check if your A record points to the correct IP address of your web server. Use our DNS lookup tool to verify your current A record.
Ensure your domain registration has not expired. An expired domain will stop resolving and your website will become unavailable.
If your NS records are incorrect or if your DNS provider is experiencing issues, your domain may not resolve correctly. Verify your NS records with our tool.
When your A record points to an incorrect IP address, visitors may see a "site can't be reached" error or be directed to a wrong website.
Check your domain expiration date and ensure automatic renewal is enabled. Expired domains can lead to complete website unavailability.
Issues with your DNS provider or incorrect NS records can cause intermittent access problems to your website. DNS server outages are rare but can affect your domain's availability.
