Internet Speed Test

Internet speed (line speed) is an index that indicates the line speed by how much data can be sent and received via Internet communication. The faster the communication speed of the Internet line (optical line, mobile router, home router, mobile phone, FLET'S Hikari, low-cost SIM, etc.), the more data can be transferred in a short time. You can quickly load web pages and watch videos, making it more comfortable to use the Internet.

• IP: The IP address of the person connected.
• Line name: The name of the company that operates the internet line from which you are connecting.
• Ping: A number that indicates the response speed. A high Ping means that it takes a long time to respond. 30ms or less is good, 50ms or less is no problem, 50ms to 100ms is slightly high, and 100ms or more is very high. The unit is "ms (milliseconds)", which is 1/1000 of a second.
• Jitter: A number that indicates the fluctuation of Ping. It is the difference between the maximum and minimum values ​​of Ping measured continuously within a certain period of time. If Jitter is high, the difference in response speed is large, and the communication state is unstable. 5ms or less is good, 10ms or less is no problem, 10ms to 20ms is slightly high, and 20ms or more is very high. The unit is "ms (milliseconds)", which is 1/1000 of a second.
• Downstream: Download speed: The direction in which data is received (downloaded) from the Internet to a device such as a computer or smartphone is "downstream". "Downstream speed" means "the speed at which you can download". The unit is "ms (milliseconds)", which is 1/1000 of a second. The unit is "Mbps (megabits per second)", which means that 1Mbit of data can be transferred per second. It is also sometimes expressed as "Mbit/s". It is the amount of data that can be sent and received per second, and 1MBit/s = 8Mbps.
• Upstream: Upload speed: The direction in which data is sent (uploaded) from a device such as a computer or smartphone to the Internet is "upstream". "Upstream speed" means "the speed at which you can upload". The unit is "ms (milliseconds)", which is 1/1000 of a second. The unit is "Mbps (megabits per second)", which means that 1Mbit of data can be transferred per second. It is also sometimes expressed as "Mbit/s". This refers to the amount of data that can be sent and received per second, and 1MBit/s = 8Mbps.
