Re: [5gangip] Fwd: New Version Notification for draft-nordmark-id-loc-privacy-00.txt

Hi Erik,

My comments on your draft:

a mobile device which is using typical
   cellular network technologies end up with an IP address, at least as
   seen by remote peers outside of the cellular network, which is
   associated with the cellular operator but does not necessarily
   indicate a particular location of the mobile device.

Is this correct? IP address assigned by a cellular network would not
indicate a particular location?

Thus we believe that we can explore the core of the ID/locator privacy issue

   by looking at long-lived identifiers.

wholeheartedly concur.

If a third party can at any time determine the IP location of some
   identifier, then the device can at one point be IP geolocated at
   home, and later a coffee shop.

What is IP location? is it IP address?
I think that the above sentence is correct because the identifiers are
carried in the clear in packet headers which is not mentioned in the draft.

If this is the case, then the ID/locator mapping system can
   provide access control so that only those trusted devices can access
   the mappings.

The above quote from Sec. 5.1. first paragraph is a very good observation,
agreed.

Today such location sharing happens at an application layer using GPS
   coordinates.  But while such sharing is in effect, it wouldn't be
   unreasonable to also consider sharing IP locators to make it more
   efficient or more robust to e.g., route a video feed from one device
   to another.

The above helps clarify why IP level solution is needed.

5.3.  Business Assets

Sec. 5.3 gives some IoT context which was missing.

The draft has a number of typos and I am going to communicate them to the
author separately.
Also I send the mail to one list, you may forward it to your favorite list
if you wish.
