DNS Lookup Utility Guide
The Domain Name System (DNS) is the phonebook of the internet, translating human-friendly domain names (e.g. `example.com`) into computer-readable IP addresses (e.g. `93.184.216.34`). When you request a domain lookup, the resolver queries name servers to find active records. Our DNS Lookup utility lets you fetch records (A, AAAA, MX, CNAME, TXT, NS, SOA) to troubleshoot server configurations, verify domain ownership, or check email settings.
⚙️ Key Features
- Resolves standard DNS records instantly: A, AAAA, CNAME, MX, TXT, NS, and SOA.
- Fetches TTL (Time to Live) details and query execution times.
- Validates domain names and identifies propagation status.
- Outputs clean, copyable JSON tables of DNS record responses.
📖 How to Use
- Enter the domain name (e.g. `google.com`) in the lookup input box.
- Select the target record type from the menu, or select 'ANY' to fetch all active records.
- Click 'Resolve' to query global DNS name servers.
- Review the output table containing record values, TTL durations, and priorities.
Lookup requests query global DNS resolvers directly. No domain queries, IP addresses, or lookup histories are saved on the server.
Frequently Asked Questions (FAQ)
What is the difference between an A record and a CNAME record?
An A (Address) record maps a domain name directly to an IPv4 address. A CNAME (Canonical Name) record maps an alias domain name to another domain name, rather than an IP address.
Why do my DNS changes take time to appear?
This delay is due to DNS propagation. Each DNS record has a TTL (Time to Live) value in seconds, telling DNS caches how long to store the record before requesting an update. Propagation can take from a few minutes up to 48 hours.
What are MX and TXT records used for?
MX (Mail Exchanger) records route email traffic to your mail servers. TXT (Text) records store descriptive text notes, commonly used for domain verification (like Google Search Console) and email security policies (like SPF and DKIM).
