This new mechanism allows P2P Client to request an IPv4 address from the GO as part of the 4-way handshake to avoid use of DHCP exchange after 4-way handshake. If the new mechanism is used, the assigned IP address is shown in the P2P-GROUP-STARTED event on the client side with following new parameters: ip_addr, ip_mask, go_ip_addr. The assigned IP address is included in the AP-STA-CONNECTED event on the GO side as a new ip_addr parameter. The IP address is valid for the duration of the association. The IP address pool for this new mechanism is configured as global wpa_supplicant configuration file parameters ip_addr_go, ip_addr_mask, ip_addr_star, ip_addr_end. For example: ip_addr_go=192.168.42.1 ip_addr_mask=255.255.255.0 ip_addr_start=192.168.42.2 ip_addr_end=192.168.42.100 DHCP mechanism is expected to be enabled at the same time to support P2P Devices that do not use the new mechanism. The easiest way of managing the IP addresses is by splitting the IP address range into two parts and assign a separate range for wpa_supplicant and DHCP server.
