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 user-selectable DNS service.
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.
Cuatro - DNS Lookup requires iOS 3.1.3 or higher on an iPhone, iPad or iPod touch.
