About this Cloud Hub Solution:

‍

The DNS Lookup API is a RESTful API that enables developers to perform DNS lookups and retrieve domain information programmatically.

‍

With this API, developers can access a range of DNS records, including:

• IP addresses, providing the numerical address of a domain
• Domain names, allowing for domain verification and analysis
• Mail servers, revealing the email infrastructure of a domain
• Name servers, showing the delegation of DNS authority for a domain
• TXT records, containing additional text information about a domain

‍

Developers can use the DNS Lookup API to build applications that require:

• Domain verification, such as validating domain ownership or checking for malicious activity
• IP geolocation, for identifying the geographic location of IP addresses
• DNS-based security checks, including threat intelligence and vulnerability assessment

‍

The DNS Lookup API is commonly used in various use cases, including:

• Cybersecurity, for threat detection and mitigation
• Email validation, to prevent spam and phishing
• Web development, for optimizing website performance and security

‍

The DNS Lookup API follows RESTful principles, with:

• Predictable, resource-oriented URLs for easy navigation
• Form-encoded request bodies for efficient data transmission
• JSON-encoded responses for simple and flexible data handling
• Standard HTTP response codes for reliable error handling
• Authentication mechanisms for secure access control
• Standard HTTP verbs for clear and concise API interactions

‍

Using the DNS Lookup API, developers can programmatically perform lookups for various DNS record types, including A, NS, MX, AAAA, TXT, and SOA records, for any domain, using simple GET requests.

‍

curl --request GET 'https://api.apilayer.com/dns_lookup/api/a/google.com' \
