免费DNS工具

DNS 工具的主要功能

ClouDNS Free DNS 工具提供一系列专为高效和易用而设计的功能:

DNS Lookup Tool

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

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

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

这些功能专为满足新手用户和经验丰富的 IT 专业人员的需求而定制。
