\About IP address
Global IP address and local IP address
There are 2 types of IP addresses: “global IP address” and “local IP address”.
Global IP address: Just as different IP addresses are needed on a network, all PCs using the Internet worldwide must use a unique IP address. This IP address is referred to as “global IP address”.
Normally, the global address is assigned by the IS provider.
Local IP address: In an environment not connected to the Internet (within a household, within a company, etc.), separate IP addresses can be used freely within a network.
This IP address is referred to as “local IP address”.
IP address classes
IP addresses are categorized into 3 classes depending on the number of PCs structuring a network.
“Class A IP addresses” are used for
Within a network, all IP addresses must be of the same class. Each IP address is structured by a series of 4 digit numbers separated by a period. The first number of the IP address indicates the class.
| Class indicated here |

IP address | xxx.xxx.xxx.xxx |

* “224 ~ 255” are normally not used for IP addresses.
For example, a network structured by a few PCs to dozens of PCs would use Class C IP addresses.
Normally, the following special IP addresses are used when structuring a network.
Class | Set IP address |

|
Class A | 10.0.0.0 ~ 10.255.255.255 |
|
|
Class B | 172.16.0.0 ~ 172.31.255.255 |
Class C | 192.168.0.0 ~ 192.168.255.255 |

About proxy server
Aproxy is a “relay point” for accessing the Internet. When enabling “Use a proxy server”, the proxy server will make access to the Internet.
Since various access information is cached at this time, downloading will be faster when reloading the same information from the Internet since the data is loaded from the proxy server.
