Our A record lookup tool reveals the IPv4 addresses associated with any domain name within seconds. Whether you're migrating servers, troubleshooting connectivity issues, or validating DNS configurations, this essential diagnostic tool provides the information you need to keep your services running smoothly.
Simply enter your domain name and receive comprehensive details including current IPv4 mappings, TTL settings, and hosting information to help you make informed decisions about your infrastructure.
A records serve as the fundamental building blocks of domain name resolution, creating direct mappings between human-readable domain names and machine-readable IPv4 addresses. These essential DNS entries tell browsers, applications, and other network services exactly where to find your website or service on the internet.
Unlike CNAME records that create aliases between domain names, A records establish concrete connections to specific IPv4 addresses. This makes them indispensable for web hosting, email delivery, and virtually every internet service that requires direct IP communication.
Regular A record checks become crucial in several operational scenarios:
Understanding the distinctions between primary DNS record types helps optimise your domain configuration:
A Records: Create direct mappings from domains to IPv4 addresses (32-bit format)
AAAA Records: Establish connections to IPv6 addresses (128-bit format) for modern networking
CNAME Records: Generate aliases that redirect one domain name to another domain name
Each record type serves specific purposes, and many domains utilise combinations of these records to ensure comprehensive accessibility across different network configurations.
Beyond DNS lookup tools, PulseStack™ offers complete uptime monitoring solutions to safeguard your online presence. Monitor website availability, SSL certificates, response times, and performance metrics with intelligent alerting that keeps you informed of any issues.

Can A records contain domain names instead of IP addresses?
No – A records must always contain valid IPv4 addresses. For domain-to-domain redirections, use CNAME records instead.
Why do I see CDN IP addresses rather than my server's IP?
When using proxy services or content delivery networks, A records display the CDN's edge server addresses to optimise content delivery and provide additional security layers.
Should I configure both root (@) and www A records?
Yes – these represent different hostnames requiring separate A record entries to ensure your site loads regardless of how visitors type your domain.
What's the optimal TTL setting for A records?
Lower TTL values (300-3600 seconds) enable faster DNS changes but increase query loads, whilst higher values improve caching efficiency but slow propagation.
Can multiple A records exist for one domain?
Absolutely – multiple A records enable basic load distribution through round-robin DNS, though this differs from sophisticated health-checked load balancing.
