The steps to alter DNS on computers, Android, and iOS are generally simple and easy to perform. But does changing Wifi DNS have any impact? Does it make devices operate slower? Let's explore.
Effects of Changing Wifi DNS on Computers and Phones
1. What is DNS?
DNS (Domain Name System) essentially functions as an Internet directory, where domain names are located and translated into IP addresses (Internet Protocol). DNS maps the names users use to locate websites with the IP address that computers use to find that website.
To paint a picture, for example, when you type 'Mytour' in the browser's address bar, the server will map the website name to the corresponding IP address. The IP address has a structure like 203.0.113.72.

2. What is the Impact of Changing Wifi DNS?
To elaborate on the impact of changing Wifi DNS, it's crucial to focus on DNS records, with the most important being the A record, short for Address.
The A record maps all domain names to IP addresses. When you access a website, DNS resolves the query, translating the URL into an IP address and pointing to the server where the website is stored. If there is high latency on the DNS server, it can affect and slow down the domain resolution process, causing websites to load slower than expected.
By default, DNS servers are selected automatically, although some Internet service providers may use specific DNS servers close to the user's geographical location.
However, if DNS servers are handling a large traffic load, this will result in a surge in domain resolution time, slowing down the web browsing process. Similarly, if DNS servers are placed considerably far from the user's location, this will take more time to resolve website queries.
While users can change Wifi DNS to enhance their web browsing speed, it's not a one-size-fits-all solution. Ideally, choosing DNS servers close to the geographical location and with regularly updated records is recommended.
Websites on the Internet are widely distributed across servers or nodes. Some users utilize a CDN (content delivery network) like Cloudflare or Google DNS to improve performance and load websites faster.
Core files are distributed across the network rather than stored on the same server. This helps reduce latency and improve website loading times.
3. How to Change DNS on Computer, Android, and iPhone
Besides enhancing performance and speeding up web browsing, changing Wifi DNS brings several benefits to users, such as:
- Improved privacy protection (avoiding Internet service providers tracking and recording browsing history).
- Access to regionally blocked websites.
- Blocking harmful websites and filtering inappropriate content, and more.
For these reasons, you should consider changing DNS to enhance web browsing experience and improve privacy. For detailed instructions on changing DNS on computers, Android, and iPhone, you can refer to the section below.
