How to Change DNS Settings on iPhone & iPad
When you point your iPhone or iPad at a web address (like osxdaily.com), iOS will perform a DNS lookup to send you to the proper location. DNS servers handle part of that lookup service, translating numerical IP addresses into the readable domain names we’re all more familiar with and associate with web sites and other internet addresses. Most internet service providers provide their own DNS servers, but let’s be honest, they’re not always the fastest, thus you can sometimes speed up your internet service or even resolve some networking issues by changing DNS settings to another set of servers. Changing the DNS settings in iOS are what we’re going to cover here, and the process is the same on any iPhone, iPad, or iPod touch.
