I want my Pi to have a permanent IP when accessing via LAN (i.e. http://192.168.1.10/, not the web), so I don't have to search for it every time. My router settings will not allow me to do this (It's an ISP provided, with limited settings).

I have my Pi 3B running Raspbian Lite.

Use the hostname as a means to eliminate an IP change messing you up. You just put the .local on it so it will search on the local network for that host.

MacUser2525:~$ ssh zeus@buster-raspi.local
Linux buster-raspi 5.9.0-0.bpo.5-arm64 #1 SMP Debian 5.9.15-1~bpo10+1 (2020-12-31) aarch64

If you want your Pi to be assigned a predictable IP Address you can request the DHCP server to assign one.
E.g. Adding the following to /etc/dhcpcd.conf will request an address on wlan0 and on eth0.

interface wlan0
request 192.168.1.99

interface eth0
request 192.168.1.98

If you request an IP Address within the range managed by the DHCP server which is available this should be honoured, otherwise the DHCP server will allocate an address as normal.

  • real noob here, how do I add to a file? – wall03 Mar 02 '21 at 00:47
  • You will have to learn how to edit system files. Most use something like sudo nano /etc/dhcpcd.conf I prefer sudoedit /etc/dhcpcd.conf (which is safer), but not sure if this requires other configuration. I suggest you practice editing on some other files. ALWAYS make a copy BEFORE editing ANY system file. – Milliways Mar 02 '21 at 00:50
