DIG查询

Tool Introduction

This tool provides online DIG (Domain Information Groper) query functionality, helping you quickly query DNS record information for a specified domain. It supports common DNS record types such as A records (IP address), AAAA records (IPv6 address), NS records (name server), CNAME records (alias), and MX records (mail exchange). You can specify a particular DNS server for queries to diagnose DNS resolution issues or verify DNS configurations.

How to Use

1. Enter the domain to query in the "Domain" field, for example: baidu.com. This is a required field.
2. (Optional) Enter the DNS server address to use in the "DNS (Optional)" field. If left blank, the default DNS server will be used.
3. Select the DNS record type to query from the "Type" dropdown menu, such as A, AAAA, NS, CNAME, or MX. This is a required field.
4. Click the "Query" button.
5. The query results will be displayed in the text box.

Usage Example

Here is a usage example:

• Example Input Data:
  • Domain: baidu.com
  • DNS (Optional): Leave blank (use default DNS server)
  • Type: A Record
• Expected Output Result:
  • baidu.com. 300 IN A 180.101.49.11
  • baidu.com. 300 IN A 180.101.49.12
• Specific Operation Demo:
  Enter the domain `baidu.com`, select `A Record` for the type, click query, and the tool will return the A records for baidu.com, showing Baidu's server IP addresses.

Common Questions

• Q: What input formats are supported?
• A: The domain field accepts valid domain formats. The DNS server field accepts valid IP address or domain formats.
• Q: What is the format of the output result?
• A: The output result is in text format, similar to the output of the dig command, including information such as domain, TTL, record type, and record value.
• Q: Are there any usage restrictions?
• A: This tool relies on the public network, and query speed may be affected by network conditions. Some DNS servers may limit query frequency.

Notes

• Please ensure the entered domain format is correct.
• If a DNS server is specified, please ensure that the DNS server is available and accessible.
• Query results may vary due to DNS caching; please pay attention to the TTL value.
• If the query fails, please check your network connection and DNS server settings.
