La
ICANN
es responsable en la asignación de números de
puertos TCP y UDP para usos específicos.
Los puertos bien conocidos (well-known ports) son los del rango
del 0 al 1023; en sistemas operativos derivados del
Unix,
abrir un puerto de este rango para recibir conexiones entrantes
requiere privilegios administrativos.
Los puertos registrados están en el rango desde el
1024 al 49151. Los números de puerto del 49152 al 65535
son puertos dinámicos (privados), no usados por aplicaciones
definidas.
Este no es un mecanismo forzado, ICANN provee esta especificación
como un conjunto de recomendaciones. A veces los puertos pueden
ser utilizados por protocolos o aplicaciones diferentes a
su designación oficial, tal sería el caso de
una aplicación que no recibió un puerto o rango
de puertos registrados por la ICANN, o el de un troyano.
