¿Dónde encontró Sharingd File la dirección IP que intentaba conectar?

Tengo esta aplicación para Mac instalada en LULU ( https://objective-see.com/products/lulu.html ) con el que descubrí /usr/libexec/sharingd tratando de la dirección IP local 192.168.2.255 . Descubrí lo que es el sharingd desde aquí https://discussions.apple.com/thread/6501958

Actualizar: usr/sbin/netbiosd también intenta acceder a la misma dirección IP.

pero quiero saber de donde Sharingd descubre/encuentra la dirección IP? resultado de ifconfig sin la dirección mac:
