DNS Verification Made Simple
RealDomainDNS performs real-time DNS lookups for public domains using the server's DNS resolver. It returns only the records actually present in DNS: no simulated, cached, or fabricated results.
Understanding DNS Resolution
The Domain Name System acts as the internet's address book, translating human-friendly domain names (like yourdomain.com) into machine-readable IP addresses (like 203.0.113.1) that computers use to locate and connect to websites and services.
When someone visits your website, their device queries DNS servers to find your site's location. This lookup process involves multiple servers working together to deliver the correct information.
Why DNS Monitoring Matters
When you make changes to your domain's DNS settings, these updates don't appear instantly worldwide. The process of DNS updates reaching all global DNS servers can take anywhere from minutes to days.
Keeping this in mind is useful when launching websites, changing hosting providers, or updating email services. This tool performs a single real-time lookup and does not check propagation across multiple regions or servers.
Which DNS record types can be checked?
This tool can look up the following DNS record types:
- A - Points a domain to an IPv4 address
- AAAA - Points a domain to an IPv6 address
- CNAME - Creates an alias pointing to another domain name
- MX - Specifies mail servers for the domain
- NS - Specifies the authoritative nameservers
- TXT - Stores text information (often used for verification)
- SOA - Contains administrative information about the zone
