What is a DNS Lookup?
DNS (Domain Name System) acts as the phonebook of the internet. When you type a domain like google.com, your computer performs a DNS lookup to find the IP address associated with that name. This tool allows you to see exactly what records are published for a specific domain.
Common DNS Record Types:
- A Record: Points a domain to an IPv4 address.
- MX Record: Specifies the mail servers responsible for receiving email.
- TXT Record: Used for verification (like Google Search Console or SPF/DKIM).
