Cuatro – DNS Lookup

By Red Pixel Studios, Inc.

Open iTunes to buy and download apps.


Cuatro™ is an invaluable utility that allows you to verify the DNS of a domain name by simultaneously checking records from four different DNS services.

Cuatro enables you to query the DNS service used by your Apple iPhone®, iPad® or iPod touch® and quickly compare the result to the DNS records as seen by Google Public DNS, OpenDNS® and a DNS service that you specify.

Cuatro is perfect for Web site administrators, developers or IT professionals when evaluating or troubleshooting DNS issues. It is extremely useful when launching a new site to verify that a DNS record modification is propagating to popular DNS services. Cuatro also lets you conveniently check your LAN responses to a domain request without having to use a computer.

We want this to be a useful tool for you. Please send feature requests or issues to We sincerely appreciate it.

Cuatro – DNS Lookup Features:

• Checks the A record, NS record and MX record for a domain name
• Checks DNS records as seen by your device – no proxies here
• Compares simultaneously the DNS records from four DNS services: your device, Google Public DNS, OpenDNS and one you specify
• Displays raw output from the DNS lookup
• Retains the last 100 domain queries and results
• Displays the local IP and public IP of your device
