Most of the times you need raspberry pi remote access over static IP. Here is quick note on how to add static IP on raspbian OS.
Edit /etc/dhcpcd.conf as sudo and add following lines to add static IPs on ethernet and wifi interfaces of raspberry pi.
interface eth0
static ip_address=192.168.0.6/24
static routers=192.168.0.1
interface wlan0
static ip_address=192.168.0.5/24
static routers=192.168.0.1
Reboot system and you can now access raspberry on assigned static IPs.
