How to Do a DNS Lookup Online: A Complete Guide

The Domain Name System (DNS) is the directory of the internet. It translates domain names like bagiqo.com into the IP addresses machines understand. A DNS lookup lets you see the different records associated with a domain.

What is a DNS lookup?

A DNS lookup queries the DNS servers to obtain information about a domain name. It returns the different record types that control how the domain works, which is essential for troubleshooting websites and e-mail.

Common DNS record types

• A (IPv4 address): the most common record; it maps a domain to an IPv4 address. Without it, a website would be unreachable.
• AAAA (IPv6 address): like the A record, but for IPv6 addresses.
• MX (mail exchange): specifies the mail servers that handle e-mail for the domain.
• CNAME (canonical name): aliases one domain to another.
• NS (name server): lists the authoritative name servers for the domain.
• TXT: holds arbitrary text, often used to verify domain ownership and e-mail authentication.
