How to Check DNS Records Online

The DNS Lookup Tool is a simple utility that allows you to query the Domain Name System (DNS) to retrieve records for a specific domain. The DNS acts as the internet's phonebook; it translates human-readable domain names (like `www.google.com`) into machine-readable IP addresses (like `172.217.14.228`). This tool lets you manually **check DNS records online** for any domain and inspect various types of records that are crucial for a website's operation.

How to Use the DNS Lookup Tool

  1. Enter a Domain: Type the domain name you want to investigate into the input field (e.g., `toolzenweb.com`).
  2. Select a Record Type: Choose the type of DNS record you want to check from the dropdown menu (e.g., `A`, `MX`, `TXT`).
  3. Click Lookup: Press the "Lookup" button to send the query. The results will appear below, showing the requested DNS information.
