OS X Yosemite: Network address formats for shared computers and servers

Use network addresses to connect to the computer or server

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 with file sharing turned on, as well as servers that use SMB/CIF, AFP, NFS, and FTP.

The network address consists of a protocol (such as afp://) 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.

Sharing Protocol	Address Format
SMB/CIFS (Windows) servers and shared folders	Use one of these formats: smb://DNSname/sharename smb://IPaddress/sharename 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.
AFP File Sharing	afp://ComputerName.CompanyName.com To see the AFP file sharing address for a Mac, choose Apple menu > System Preferences, click Sharing, then select File Sharing. The address appears in the window.
NFS server	nfs://DNSname/pathname
WebDAV server	http://DNSname/pathname 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.
