Understanding DNS
DNS (Domain Name System) translates domain names to IP addresses. When you visit a website:
- Your computer queries DNS servers
- DNS returns the IP address
- Your browser connects to that IP
Common DNS Uses
A Records
Point domains to web server IP addresses.
MX Records
Define mail servers for email delivery. Priority numbers indicate preference (lower = higher priority).
TXT Records
Store text information like SPF (email authentication), DKIM, and domain verification codes.
NS Records
Specify which name servers are authoritative for the domain.
FAQs About DNS Lookup
What is TTL?
TTL (Time To Live) indicates how long DNS records should be cached, measured in seconds. Lower TTL = faster propagation but more queries.
Why are there multiple A records?
Load balancing and redundancy - traffic is distributed across multiple servers.
How long does DNS propagation take?
Changes can take 24-48 hours to propagate globally, depending on TTL values.
What if no records are found?
The domain may not exist, or that record type isn't configured.
