[Tool Features]

1. Currently among similar websites, online ping only supports one or a small number of tests, which cannot objectively display the network status of the target server for a period of time. The IT Dog Ping tool can continuously conduct ping tests for a period of time and generate The more intuitive network quality histogram makes it easier for users to grasp the network status of servers in various regions and lines.

2. For servers that are prohibited from pinging, ITdog has developed an online tcping tool that can conduct TCP delay tests on the open ports of the server. It can also continue testing for a period of time to generate a network quality histogram.

3. Compared with other similar websites, the route tracking tool can obtain test results faster and more accurately through multi-thread processing (results are returned in an average of 5 seconds). In the returned data, in addition to the native route records, there are also Contains the PTR record of the node, IP geographical location, AS number to which the IP belongs, and AS information to which the IP belongs.

4. Domain name blocking and DNS pollution detection tools adopt the most scientific and efficient detection method. It is not simply about whether a website can be accessed in mainland China. The new detection method can avoid some special situations and obtain more accurate information. Results, such as:

Example 1: The domain name is not blocked, but the IP is blocked; Example 2: The domain name is not blocked, but the server where the website is located blocks access from mainland China; Example 3: The domain name has not yet started to build a website, so it is impossible to detect whether it is blocked;

As of September 18, 2021, the number of monitoring servers in different regions and different lines has reached 71, and it is still increasing.
