Boost the security and safety of the iPhone and iPad by using alternative DNS servers.

DNS servers play a role in the security of the internet and some are more secure than others. This guide shows how to change the DNS servers on your iPhone to make the internet safer to use.

There are all manner of threats on the internet and while the iPhone and iPad are immune from nearly all the viruses that are out there, it is not completely secure.

Malware is rare on the iPhone, but phishing emails are not. Fake websites can trick you into revealing your Apple ID, which is used to access iTunes, the App Store, and iCloud services. They can con you out of money by pretending to be your bank, PayPal, Amazon and so on.

iPhone and iPad users have to keep their wits about them to avoid scams, phishing, fake sites and tricks that are common online. Security and safety is important and should not be ignored.

For this reason, it is useful to use DNS servers that are designed to protect you from threats when using online services and websites.

What is a DNS server?

Every device, computer and website has a unique IP address. When one device, such as an iPhone or iPad, needs to connect to a website, such as, a DNS server converts the URL you enter to the IP address. This is then used to connect to the web server.

The IP address of Apple’s website is Just type those numbers into Safari and tap Go to see for yourself. IP addresses of websites are impossible to remember, which is why we use URLs. Browsers like Safari use a DNS server to convert URLs into IP addresses.

Safer more secure DNS

Not all DNS servers are the same. All are fast, but some are faster than others and they offer performance benefits. A super fast one won’t make a huge difference to browsing the web, but they do help a little.

Some DNS servers provide unrestricted access to everything on the internet, but others don’t and they may limit access to certain websites and services.

By changing from the default automatic DNS server to an alternative one, you can speed up the internet a tiny bit and also increase security an safety.

With each DNS service that is listed, DNS Override lists the benefits of using it. For example, a service may filter malware, phishing, scams or adult content.

Don’t just use the default DNS servers set by automatic mode on the iPhone because they may not offer the best speed, security or safety. Use an alternative.

If you don’t want to configure the settings yourself, unlock DNS Override and let it set the DNS for you.
