 ip_local_port_range - 2 INTEGERS
 	Defines the local port range that is used by TCP and UDP to
 	choose the local port. The first number is the first, the
-	second the last local port number. Default value depends on
-	amount of memory available on the system:
-	> 128Mb 32768-61000
-	< 128Mb 1024-4999 or even less.
-	This number defines number of active connections, which this
-	system can issue simultaneously to systems not supporting
-	TCP extensions (timestamps). With tcp_tw_recycle enabled
-	(i.e. by default) range 1024-4999 is enough to issue up to
-	2000 connections per second to systems supporting timestamps.
