What is a DNS Lookup Tool?
A DNS Lookup tool queries the Domain Name System (DNS), the internet's "phonebook," to retrieve the records associated with a domain name. Each record type serves a different purpose, from pointing a domain to an IP address (A record) to handling email (MX record).
This tool is essential for web developers, network administrators, and cybersecurity professionals to diagnose connection issues, verify domain configurations, and investigate a domain's infrastructure.

What is an A Record?
The "A" or "Address" record is the most basic DNS record. It points a domain name (like www.example.com) to a specific IPv4 address (like 192.0.2.1).
What is an MX Record?
The "Mail Exchanger" (MX) record specifies which mail servers are responsible for accepting email for a domain. It includes a priority number to indicate the preferred server.
What does TTL mean?
TTL stands for "Time To Live." It's a value in seconds that tells DNS resolvers how long they should cache (store) a DNS record before querying for it again. A lower TTL means changes propagate faster.
