Free DNS tool

DNS 工具的主要功能

ClouDNS 免費 DNS 工具提供一系列為效率與易用性而設計的功能:

DNS Lookup Tool

Perform a DNS lookup for any domain and verify the most commonly used DNS record types:

• A Records
• AAAA Records
• MX Records
• TXT Records
• CNAME Records
• NS Records
• SOA Records
• PTR Records
• CAA Records

Instantly check whether your DNS records are configured correctly.

DNS Speed Test

Measure the response time of your DNS queries for specific location, DNS record and name server

The DNS Speed Test helps identify:

• Slow DNS responses
• Resolver-specific issues
• Regional DNS performance differences
• DNS latency problems

Fast DNS resolution improves website loading speed, email delivery, and overall user experience.

DNS Audit Tool

Run a full DNS audit to identify configuration problems and potential risks.

Our DNS audit checks:

• Nameserver configuration
• DNS record consistency
• DNS propagation status
• SOA configuration
• DNSSEC configuration
• Mail server records
• SPF records
• Response times

The audit helps administrators quickly detect and resolve DNS issues before they impact users.

DNS Propagation Checker

DNS changes do not become visible everywhere immediately. DNS propagation depends on different factors, including TTL values, ISP caches, recursive resolvers, and geographic location.

Use the ClouDNS DNS Tool to verify whether:

• New DNS records are visible
• DNS changes have propagated globally
• Nameserver updates are active
• DNS migrations are complete

這些功能經過量身設計，可同時滿足新手使用者與經驗豐富 IT 專業人員的需求。
