What is a DNS Lookup?
A DNS lookup queries the Domain Name System to find the specific IP address or records associated with a domain. It is essential for troubleshooting website connectivity, email delivery issues, and server migrations.
Centrigon's tool provides real-time data directly from global DNS servers to ensure your configurations are correct.
Common Record Types
- A Record: Maps a domain to an IPv4 address.
- MX Record: Identifies the mail servers for the domain.
- TXT Record: Used for SPF, DKIM, and site verification.
- CNAME: Aliases one domain name to another.
Why Check Your DNS?
Incorrect DNS settings can lead to website downtime and failed email delivery. Regular diagnostics help identify propagation delays or misconfigured security records before they impact your users.
