In iOS8.0 or later, or on the iPhone, the Wi-Fi feature is called \"wireless LAN.\" With this feature, users can connect to a Wi-Fi hotspot directly based on the recommended Settings. Key Settings, if necessary, can be modified by the user. Specific instructions are as follows:
DHCP: This service requires the router to be enabled and the IP pool to be specified correctly. Therefore, users are generally not advised to set this option.
BootP: indicates the DHCP service between hosts without disks. Bootp is rarely used. You are not advised to manually change it.
DNS: An important service that resolves the association between domain names and IP addresses. The default value is 192.168.1.1, but it can also be set to other private services, such as 8.8.8.8 (Google Secure DNS), 112.114.47.27 (oneDNS of Malicious Website Lab), 114.114.114 (114 fast DNS), etc.
