What Are DNS Records?

DNS records are essential text entries stored in DNS servers that map domain names to IP addresses and provide key routing instructions. They ensure that when you type a URL like howtodns.com, your browser is directed to the correct server.

From simple A and AAAA records to more specialized types like MX and CNAME, each record plays a unique role in making your website accessible and secure. Understanding these records not only helps in troubleshooting issues but also boosts your site’s performance and SEO.

DNS Record Types

Knowing your DNS record types is essential for effective domain management and website performance. Each record type plays a unique role in connecting users to your site.

• A: Connects your domain to an IPv4 address.
• AAAA: Connects your domain to an IPv6 address.
• CNAME: Provides an alias for another domain.
• MX: Directs email traffic with mail exchange records.
• TXT: Holds text data for verification and email security (SPF, DKIM, DMARC).
• NS: Specifies the authoritative name servers for your domain.
• SOA: Indicates the start of authority for your DNS zone.

Common DNS Issues

Even well-configured domains can encounter DNS challenges. Our guide breaks down common issues and provides simple troubleshooting tips to keep your website running smoothly.

• DNS propagation delays
• Incorrect record configuration
• Expired TTL values
• Registrar DNS misalignment
• Firewall or ISP DNS filtering

How DNS Propagation Works

When you update a DNS record, changes are not instant. They travel across global DNS servers based on your record’s Time To Live (TTL) and ISP caching policies. Our tool helps you visualize this process, ensuring you understand every step in achieving optimal DNS performance.

What Are Root DNS Servers?

Root DNS servers are the foundation of the Domain Name System. They direct queries to top-level domain (TLD) servers like .com, .net, and .org, which then pass requests to authoritative servers. Understanding root servers is key to grasping how the Internet efficiently resolves domain names.
