Yes, but you can also push/pull from a filesystem location. To be able to push it, it is simpler to init the repo with `git init --bare`.

I've used this on NFS drives, but also SMB shares from windows, and just about anything that can be mounted to a folder. Having an external hard disk drive or usb stick also works.

And lastly, git also comes with a daemon mode which makes it easy to temporarily host a server for a repo. Just connect multiple laptops trough Wi-Fi, and work together (with a pull workflow rather than a push workflow). That's quite useful [1]
