Apple Computer has released AirPort 1.2, the latest version of its wireless networking software. AirPort 1.2 includes base station software, which now ships with a default configuration that disables AirPort-to-Ethernet bridging, does not assign DHCP addresses, or share a single IP address on an Ethernet network via Network Address Translation (NAT). All these services can still be enabled from the AirPort Admin utility, but these changes make it easier to introduce AirPort base stations into existing networks without disrupting services. AirPort 1.2 also supports closed networks in which the name of the AirPort network is hidden; this provides an additional level of obscurity in that users must know the exact name of the AirPort network in order to connect to it. Apple also says the AirPort 1.2 software improves stability and performance. The software is a 4.5 MB download and requires at least Mac OS 8.6 or higher (with Mac OS 9.0.4 recommended). Apple has also released a PDF document called Designing AirPort Networks, and is conducting an online survey of AirPort Base Station users so Apple can prioritize future development.
