Network Intelligence
The network data shown here is also available via the Netify Data Feed API. We provide network intelligence to help deliver better digital experiences to end users and businesses.
Network Ranges
CSDN does not have any defined network blocks. The application is distributed across the individial IP addresses summarized below.
Some applications are deployed across network blocks. Only networks that are dedicated to an application or platform are provided.
Core Networks
Applications are sometimes deployed on partner networks, parent company networks, or regional hosting providers. The following is a sample of CSDN IP addresses deployed on this type of network.
Network | PoP | Category | Location | IP | Shared |
---|---|---|---|---|---|
China Mobile | Core Network | ISP/Telco | China | 117.149.203.12 | |
China Mobile | Core Network | ISP/Telco | China | 117.149.203.32 | |
China Mobile | Core Network | ISP/Telco | China | 117.149.203.33 | |
China Mobile | Core Network | ISP/Telco | China | 117.149.203.51 | |
China Mobile | Core Network | ISP/Telco | China | 117.149.203.69 | |
and 10 more |
Other Networks
There are tens of thousands of Internet network providers and we make an effort to track as many as we can, but we have less coverage for niche and local providers. The following is a sample of CSDN IP addresses on this type of network.
ASN Description | ASN | Route | Location | IP | Shared |
---|---|---|---|---|---|
Asline | AS18013 | 103.134.145.0/24 | Hong Kong | 103.134.145.33 |
Hosting
Hosting vendors like AWS and Microsoft Azure provide cloud-based computing and network resources to deliver applications. The hosting platforms used by CSDN are summarized below by geographical points-of-presence (PoP).
Each PoP can host many IPs to deliver an application. A sample IP is provided.
Cloud Hosts | # of IPs |
---|---|
Huawei Cloud | 42 |
China Telecom IDC | 6 |
Zenlayer | 1 |
Hosting Platform | Network | PoP | Location | Sample IP | IPs |
---|---|---|---|---|---|
China Telecom IDC | China Telecom IDC | Core Network | China | 49.4.45.146 | 6 IPs |
Zenlayer | Zenlayer | Core Network | India | 129.227.248.169 | 1 IP |
Huawei Cloud | Huawei Cloud | Core Network | China | 49.4.17.138 | 31 IPs |
Huawei Cloud | Huawei Cloud | Core Network | Singapore | 159.138.179.238 | 11 IPs |
Content Delivery Networks - CDNs
In order to get information to end users more quickly, many applications are distributed from multiple geographical points-of-presence (PoPs) using Content Delivery Networks (CDNs).
Each PoP can host many IPs to deliver an application. A sample IP is provided.
Take special note of CDNs that use Anycast technology. Anycast makes it possible to route a single IP address to a variety of different geographic locations. In other words, one global Anycast IP is hosted in multiple geographic locations.
