一、With the acceleration of globalization process, transnational access to the Internet has become routine. However, differences in network environments across different regions often lead to a series of technical issues, including DNS

Analyzing problems is a common approach. Especially when Vietnamese users try to access Chinese domestic websites, they often encounter slow DNS resolution speed, which seriously affects users

Experience. This article will explore the causes and solutions to this problem.

1. Reasons for slow DNS resolution

Geographic distance: Although Vietnam and China are adjacent, the data transmission path may be longer due to the uneven distribution of Internet infrastructure, which increases the delay of DNS queries.

DNS server configuration: Local DNS servers in Vietnam may not cache enough records of Chinese websites or communicate effectively with authoritative DNS servers in China

The rate is not high.

Network congestion: International export bandwidth is limited, especially during peak hours, network congestion may lead to DNS request timeouts or losses.

Firewall restrictions: Some countries or regions may strictly control cross-border network traffic for security reasons, which may also be a reason for slow DNS resolution.

2. Solution method

Using public DNS services

DNS: DNS services are known for their speed and reliability. Users can set up servers by changing the DNS settings of their devices or routers.

Optimize local DNS cache

For frequently visited Chinese websites, cache records can be manually added to the local DNS server to reduce reliance on external DNS servers.

Regularly clean and update the local DNS cache to avoid resolution failures caused by cache expiration.

Utilizing CDN acceleration

Content Delivery Network (CDN) can cache website content to nodes around the world. When users request access, CDN will select the nearest node to provide services,

Greatly reducing the time for cross regional transmission.

Shigeng Communication supports CDN services for nodes in China and Vietnam, which can significantly improve the speed of Vietnamese users accessing Chinese websites.

Adjust network settings

Check and optimize the settings of network devices, such as MTU values and QoS (Quality of Service) settings of routers, to ensure the stability of network connections.

If conditions permit, upgrading network hardware, such as using routers and modems that support higher bandwidth, can be considered.

3. Conclusion

Slow DNS resolution is an important factor affecting the experience of Vietnamese users accessing Chinese websites. By using public DNS services, optimizing local DNS caching, utilizing CDN acceleration

Adjusting network settings and collaborating with ISPs can effectively alleviate this issue. Enterprises and individual users can choose suitable solutions based on their own situations to enhance their performance

The efficiency and quality of cross-border network access.
