How to Disable DNS Block on an iPhone

Parental controls can create DNS blocks.

The Domain Name System connects a website’s domain name, such as “Google.com,” to its IP address, such as “64.233.160.0.” When a DNS block is in place, your iPhone’s browser can’t match the name with the address, and you are unable to access the site. Parental control and other site-blocking software use the DNS to filter certain pages. Some ISPs also restrict access to certain parts of the Internet, such as filesharing sites. However, the iPhone’s customizable Internet connection makes the process of disabling a restricted DNS and replacing it with a more accommodating one simple, even if it’s your own ISP that’s imposing the block.

Tap the “Settings” icon and select “Wifi.”

Tap the blue arrow next to the connection you want to modify to enter the network’s settings.

Select the “DNS” option under the DHCP heading.

Tap the text box and delete the existing entry.

Enter a new DNS entry. If you just want to change it back to the original DNS provided by your ISP, you can simply use the IP address displayed in the Router field on the previous page. If you want to go through a public, unrestricted DNS, you can enter “8.8.8.8, 8.8.4.4” for Google’s public DNS or “208.67.222.222, 208.67.220.220” to use the OpenDNS servers.

Exit the screen to save the new settings and then tap the “Renew Lease” option to reset the connection and enable the new DNS.
