Re: [port-srv-reg] "assigned"

[Lars Eggert <[e-mail]>]

Hi,

has there been any action around this wrt updating http://www.iana.org/assignments/port-numbers? The page still says:

	The range for assigned ports managed by the IANA is 0-1023.
and
	The Registered Ports are in the range 1024-49151.

After our discussion, I understand that registered and assigned mean the same thing, right? So the former should probably be change to "system" or "well known" ports. There should probably also be a sentence in the beginning of the page that clarifies that IANA manages to ports from 0-49151.

PS: CC'ing Fernando, since this is relevant for his port-randomization draft.
