Network address formats and protocols on Mac
If you know the address for a shared computer or server on your network, you can use it to connect to the computer or server. You can connect to Mac and Windows computers that have file sharing turned on, as well as servers that use SMB/CIF, NFS, and FTP.
The network address consists of a protocol (such as smb://) followed by the Domain Name System (DNS) name and any additional pathname for the computer. Check the table below for the correct address format to use to connect to different types of servers.
SMB/CIFS (Windows) servers and shared folders
Use one of these formats:
You can also use the computer name. If you don’t specify the shared folder as part of the address, you can choose it after you enter your user name and password.
You can use the Internet Protocol (IP) address for the computer instead of its DNS name.
From the Finder, you can connect to FTP servers only with read-only access. To copy files to an FTP server, use an FTP app.
