Domain name for Raspberry pi

Solution 1:

If you just want to use the simpler command to establish ssh connection you can try to make a config file:

$ cat ~/.ssh/config
Host pi4
  HostName 192.168.88.252
  User ak
  IdentityFile ~/.ssh/id_ecdsa

Host pi3
  HostName 192.168.88.248
  User ubuntu
  IdentityFile ~/.ssh/id_ecdsa

And If you want to use domain names, you must assign them to your raspberry somehow. I use MikroTik, so I just add static DNS records:

[admin@MikroTik] > ip dns static print
Flags: D - dynamic, X - disabled
 #    NAME                   REGEXP                  ADDRESS                                                  TTL
 0    router.lan                                     192.168.88.1                                             1d
 1    pi4.local                                      192.168.88.252                                           1d
 2    pi3.local                                      192.168.88.248                                           1d

As an alternative, you can edit hosts file on your machine like that:

$ cat /etc/hosts
127.0.0.1       localhost
127.0.1.1       pi4

192.168.88.252  pi4.local
192.168.88.248  pi3.local

P.S But of course, you need to make sure that your raspberry have a static IP address if you don`t want to edit all this configs every time
