Short for Automatic Private IP Addressing, a feature of later Windows
operating systems. With APIPA, DHCP clients can automatically
self-configure an IP address and subnet mask when a DHCP server isn't
available. When a DHCP client boots up, it first looks for a DHCP
server in order to obtain an IP address and subnet mask. If the client
is unable to find the information, it uses APIPA to automatically
configure itself with an IP address from a range that has been
reserved especially for Microsoft. The IP address range is 169.254.0.1
through 169.254.255.254. The client also configures itself with a
default class B subnet mask of 255.255.0.0. A client uses the
self-configured IP address until a DHCP server becomes available.
The APIPA service also checks regularly for the presence of a DHCP
server (every five minutes, according to Microsoft). If it detects a
DHCP server on the network, APIPA stops, and the DHCP server replaces
the APIPA networking addresses with dynamically assigned addresses.
APIPA is meant for nonrouted small business environments, usually less
than 25 clients.
Берем что-то, что умеет сделать ping 169.254.255.253 и сказать - на arp
who-was ответили или нет, и на его основе - делаем.
Более проще - возми себе адрес 169.254.254.253 и на нем сиди.
