Whenever your network administrator, educational facility, or state enforces web filtering it's often because of domain name system censorship. DNS stands for domain name system and it maps human-readable names to machine-readable addresses, translating website names like google.com into numeric identifiers that your computer can understand. If a site is blocked it’s usually because the your current DNS resolver has been configured to block the domain.

To circumvent these restrictions you can switch to an alternative DNS resolver to use a public DNS server that maintains an unrestricted resolution policy. Widely recommended servers are Google DNS 8.8.8.8 and 8.8.4.4 or 1.1.1.1 and 1.0.0.1 from Cloudflare. These services operate without content bias and they usually refrain from filtering by regulatory rules.

In Windows 10 you can change your DNS settings by going to Network and jun88 đăng nhập Internet Settings, selecting your active connection, opening the adapter settings, then IPv4 properties. This is where you specify the new DNS addresses. On Apple devices go to System Settings, Network, choose your active interface, click Advanced, then DNS Servers, and input the custom DNS values. For Android and iOS smartphones you’ll find DNS options under Wi-Fi network configuration by tapping the network you're connected to.

After making these DNS changes restart your application and system to make sure the changes take effect. You’ll likely gain access to sites that were previously blocked. Remember that changing DNS doesn’t anonymize your traffic or secure your connection. For enhanced security consider using a encrypted tunnel service combined with custom DNS.

Some filters are immune to DNS changes because enterprise networks implement layered blocking like network-level address denial or DPI-based filtering. For most everyday restrictions switching to a open resolver is a simple, effective, and free solution. Always make sure you’re following your organization’s policies when making these changes.
