Finding ip-link-local devices on a network -


let's have embedded devices have ip details stored in file on removable storage (a plugged in memory stick). if file exists, embedded software configure network based on content , - systems need communicate embedded devices know ip addresses should be, , use them accordingly.

however, in case device has as-yet-unconfigured memory stick, reverts getting link-local address, @ point other system (the auto-configurator, i'm writing @ moment) should find device , configure memory stick accordingly via remote ssh.

my problem link-local addresses random in rather large range (roughly 169.254.0.0/16, 65,000 different possibilities).

it seems rather onerous auto-configurator have trawl through possible ip addresses looking 1 actual machine behind it.

is there way find devices link-local addresses?

note detection of these devices meant done separate box, have no control on how embedded devices work.

obviously, link-local machine know own ip address want know if there's way detect externally without having have device sending details out.
