Many webmasters have a long struggle to choose between 360 website guard, security treasure, and jiasule free CDN. But the good news is that over the weekend Lu Songsong quietly consulted 360 and anquanbao's customer service and found that they all support dual-CDN services, in this way, we can use the DNSpod function to provide a free dual CDN acceleration service.

But this is not the focus, but how to use these free nodesReasonably arrange the line types in various regionsFirst, I found out the IP nodes of the 360 website guard, QuickShield, and jiasule free versions, and then analyzed them.

The following are the IP segments of the three CDN nodes:

(Note: The following nodes are provided by the official team and are only free of charge. it is unclear about the payment option. The time is)

Suining 221.10.36.106 Netcom

Suining 221.10.36.107 Netcom

It was found that 360 of website guard and an Quanbao's IP segment in Nanjing, Jiangsu province was placed under the same data center. it may be that 360 rented a security Bao cabinet. What should I do after knowing these nodes? Next, let's look at it.

Step 2: Understand the operator and regional distribution of this site

View the IP source distribution chart in the statistical tool, as shown in:

This is the regional access distribution chart of Lu Songsong's blog in the last three months. The traffic sources of each website are different and only for reference.

We can see that the rest of the region is hateful (the source of the region cannot be determined) guangdong No. 1, Beijing No. 2, Jiangsu No. 3, Zhejiang No. 4, Shandong No. 5, Shanghai No. 6, Henan No. 7, Fujian No. 8, and Hubei No. 9.

There are the largest number of telecom users, and the hateful "others", followed by China Netcom, China Mobile, China Tietong, and China Telecom, which can be ignored by the following operators.

Use DNSpod to enable dual-CDN service for webguard + 360

Because of the partnership between QuickShield and DNSpod, it is also very easy to enable the QuickShield service, and the 360 website guard is also very easy to enable, but domestic users need to file for use.

After learning about the operator and regional distribution of our website, we will know how to use CDN together with 360 website guard and aquanbao. We can see from the 360 and secure node IP addresses that the distribution of the two nodes is similar, so we need to make a trade-off at this time.

Because my server is deployed in Guangdong, it is a telecommunications server, and the rest is China Unicom and China Mobile. Traffic statistics show that Lu Songsong's visit to Beijing is also large, but access is slow due to the telecom server. In the node distribution, we can see that QuickShield provides a group of Beijing Unicom servers, so we can use DNSpod to enable QuickShield's CDN acceleration to only target Unicom users.

However, such free CDN has too many restrictions, such as the 30 m content cached by the security site, and the back-to-source of jiasule once the traffic increases, who calls it free.

So how do we know the operation status of carriers across the country?Appendix: A network speed measurement sample released by carriers nationwide in 360.

We can see the network speed of network operators in various regions. It can also be used separately. Generally, the larger the speed, the more users in the region. In this wayInferred distribution of China South Telecom and China North UnicomIt remains unchanged. On the contrary, China is becoming more and more powerful.

For example, in Guangdong, China Telecom is 9468985, China Unicom is 2435014, and China Telecom is 4 times that of China Unicom.It is inferred that the vast majority of users in Guangdong are telecom users,And so on.

Knowing that these big data is actually useless for small and medium-sized webmasters, there are different network operators in different places and communities that cannot be taken care of at all, so it is enough to satisfy the network with the largest number of users.

Conclusion:

When using free CDN, we not only focus on its services, functions, and stability, but also on their node distribution. the more nodes are provided and the wider the distribution, the faster the access speed. Small and Medium websites have limited funds and must be carefully calculated when purchasing a service. for free services, we should also make full use of its resources, such as the free CDN service.

Enabling dual-CDN servers is not difficult. it relies mainly on the powerful features of DNSpod, and so on. we can also enable webluker + 360 + QuickShield + jiasule,It is recommended that you do not enable too many CDN resources for free, which may cause confusion and slow resolution.

Other methods are similar. I hope this article will be useful to you.
