Abstract:
1. A method for analyzing a network environment, suitable for installation of a network device, comprising the following steps: executing a first analysis procedure by a terminal device, to determine whether or not a PPPoE connection is used to connect to a network; executing a second analysis procedure by the terminal device, to determine whether or not a target IP address is a public IP address; and executing a third analysis procedure by the terminal device, to determine whether or not DHCP is used to acquire a target IP address; wherein, if the PPPoE connection is used to connect to the network, then it is determined that the network is a first network structure; if the PPPoE connection is not used to connect to the network, and the target IP address is a public IP address, and the DHCP is used to acquire the target IP address, then it is determined that the network is a second network structure; if the PPPoE connection is not used to connect to the network, and the target IP address is a public IP address, and the DHCP is not used to acquire the target IP address, then it is determined that the network is a third network structure; if the PPPoE connection is not used to connect to the network, and the target IP address is not a public IP address, and the DHCP is used to acquire the target IP address, then it is determined that the network is a fourth network structure; and, if the PPPoE connection is not used to connect to the network, and the target IP address is not a public IP address, and the DHCP is not used to acquire the target IP address, then it is determined that the network is a fifth network structure.
