The Domain Name System or DNS is a server that translates a domain name into an IP address. For instance, apple.com is converted by the DNS to series of numbers that can find servers on the web. Every iOS device has its very own DNS server that the device uses as a default. There is, however, the ability to point the device to an alternate DNS server. This is something that people often do for greater operating speeds and a vastly improved user experience. Many DNS servers for ISPs are actually quite slow, which makes browsing a less than ideal experience, especially given that DNS lookups happen all the time. If you want to improve your user experience, you may want to learn how to change the DNS on your iPhone and iPad. In addition speeding things up a bit, this can also prevent you from getting routed to unwanted sites. Changing your DNS will prevent sites from opening up on connections that are not your own.

You May Find That Changing Your DNS Resolves Problems With Wi-Fi On Your Device
If youve been having Wi-Fi connectivity issues on your iPad or iPhone, changing your DNS could provide a fast, simple solution. When these types of problems arise, they will usually occur on every device that shares the same DNS setting.

What To Do When A New DNS Fails To Take Effect
Once you learn how to change the DNS on your iPhone and iPad, youll see that the process is actually quite simple. There may be, however, times when the new DNS does not take effect right away. This is due to problem with the DNS Cache. An easy way to resolve this problem is to perform a DNS flush. This is done by placing the device on Airplane Mode for an hour or two. You can then turn Airplane Mode back off and the issue should be resolved.
As you shop around for a new DNS to use, keep in mind that DNS cache problems become more likely each time your remove and add another domain name server. If a new addition fails to take effect as soon as it is entered, this is probably the problem that youre experiencing. The DNS flush will almost always clear your DNS cache and it only requires you to spend a relatively nominal amount of time with your device in Airplane Mode.
