Versions 1.1 and later of AirPort, however, work with Keychain.
Note: For AirPort versions 1.1 and 1.2, the Keychain is dependent on the IP address of a device for recognition and not its name. This means that an AirPort Base Station set up for a dynamically provided IP address is not recognized by the Keychain after its address changes. AirPort 1.3, however, resolves this limitation by allowing the Keychain to identify the AirPort Base Station by its hardware (MAC) address.
Note: Wireless Internet access requires an Internet service provider (fees may apply) and AirPort (or AirPort-compatible) wireless Ethernet card and base station. Some ISPs are not compatible with AirPort. For more information, see technical document 106590: "AirPort: Requirements for Wireless Internet Access"
