Set Upstream Forwarding Servers
In network configuration, DNS (Domain Name System) servers are used to translate domain names into IP addresses. ServBay's DNS server by default will read the DNS servers set in the system as upstream DNS servers. However, if users have specific needs and want to customize the upstream DNS servers (such as changing them to 1.1.1.1 or 8.8.8.8), this can be configured through ServBay's settings. This article will detail how to set the upstream forwarding server in ServBay.
What is an upstream forwarding server?
An upstream DNS server refers to when the local DNS server cannot resolve a domain name, the request will be forwarded to the upstream DNS server for resolution. By configuring upstream DNS servers, you can control the path of DNS requests to meet specific network needs.
Why customize upstream forwarding servers?
1. Improve resolution speed
Some public DNS servers (such as 1.1.1.1 and 8.8.8.8) often have faster resolution speeds and higher reliability. By customizing the upstream DNS servers, you can enhance the speed and stability of DNS resolution.
2. Enhance privacy protection
Certain DNS servers provide privacy protection functions to prevent DNS requests from being monitored or recorded. By selecting appropriate upstream DNS servers, you can enhance user privacy protection.
3. Meet specific needs
In some cases, users may need to use specific DNS servers to meet network policy or access control needs. Customizing upstream DNS servers can flexibly meet these requirements.
How to set up upstream forwarding servers in ServBay
ServBay provides a simple interface to configure upstream forwarding servers. The following are the specific setup steps:
Step 1: Open the ServBay management interface
Find ServBay in the application and double-click to open it.
Step 2: Navigate to DNS settings
After opening the program, you will see the main interface of ServBay. In the left navigation menu, click Settings. Then select the DNS Forwarding option.
Step 3: Enable custom upstream DNS servers
On the DNS Forwarding settings page, check the Customize upstream DNS option. This will enable the input box for custom upstream DNS servers.
Step 4: Enter the upstream DNS server addresses
In the input box, enter the upstream DNS server addresses you wish to use. You can enter multiple IP addresses separated by commas. For example:
1.1.1.1, 8.8.8.8Step 5: Save settings
After filling in the upstream DNS server addresses, click the Save button. ServBay will update the DNS configuration and use the specified upstream DNS servers for forwarding.
Example configuration
Below is an example configuration using Cloudflare's DNS server (1.1.1.1) and Google's DNS server (8.8.8.8) as upstream forwarding servers:
- Open the ServBay management interface.
- Navigate to
Settings->DNS Forwarding. - Check the
Customize upstream DNSoption. - Enter in the input box:
1.1.1.1, 8.8.8.8 - Click the
Savebutton.
Precautions
1. Ensure DNS server availability
When configuring upstream DNS servers, ensure that the DNS server addresses you enter are available and reliable. You can test the availability of DNS servers using the ping or nslookup commands.
2. Correct input format
When entering multiple DNS server addresses, use commas to separate them and ensure that the input format is correct. For example:
1.1.1.1, 8.8.8.83. Restarting services
In some cases, after updating the DNS configuration, it may be necessary to restart ServBay's DNS services to make the changes effective. You can restart through the ServBay management interface.
Summary
By customizing upstream forwarding servers, you can enhance the speed and reliability of DNS resolution, improve privacy protection, and meet specific network needs. ServBay provides a simple interface to configure upstream forwarding servers, making this process more convenient and intuitive. Following the steps above, you can easily set and manage upstream DNS servers to ensure the flexibility and control of your network environment.
