Frequently Asked Questions
What is DNS and how does it work?
DNS (Domain Name System) is the internet's phone book. It translates human-readable domain names like example.com into IP addresses like 93.184.216.34 that computers use to communicate. When you type a URL in your browser, your device sends a query to a DNS resolver, which looks up the corresponding IP address through a hierarchy of DNS servers (root, TLD, and authoritative nameservers) and returns the result so your browser can connect.
How do I check DNS records for a domain?
Use this free DNS Lookup tool: enter a domain name, select the record type (A, AAAA, CNAME, MX, NS, TXT, SOA, or ALL), and click Lookup. The tool queries Google's public DNS-over-HTTPS API and displays all matching records with their TTL values. You can also use command-line tools like nslookup, dig, or host on your computer.
What are the different DNS record types?
Common DNS record types include: A (maps domain to IPv4 address), AAAA (maps domain to IPv6 address), CNAME (alias pointing to another domain), MX (mail server records), NS (nameserver records), TXT (text records used for verification, SPF, DKIM), and SOA (Start of Authority with zone administration info). Each type serves a specific purpose in DNS resolution and domain configuration.
