You can configure the network settings by editing cmdline.txt in the BOOT partition and adding settings to the startup command line with ip.

The ip option takes the following form:

ip=client-ip:nfsserver-ip:gw-ip:netmask:hostname:device:autoconf  

• The client-ip option is the IP address you want to allocate to Raspberry Pi
• The gw-ip option will set the gateway server address if you need to set it manually
• The netmask option will directly set the netmask of the network
• The hostname option will allow you to change the default raspberrypi hostname
• The device option allows you to specify a default network device if more than one network device is present
• The autoconf option allows the automatic configuration to be switched on or off
