[Standards] XEP-0255: Location Query

Hi Helge,

Having worked for www.Amethon.com last year I can tell you categorically
that mobile handset ip addresses have very little location based
information.

You need a cell tower mapping system which isn't readily accessible by
the applications etc.

Ignore this problem for a few years and it will sort itself out, in the
mean time I think your idea for mapping landline ip addresses etc is a
great one.


Cheers,
Dean

Subject: [Standards] XEP-0255: Location Query

Just a heads up notice:

As suggested by Stephen Pendleton I plan to add ip-address to the type 
of "beacons" that can be submitted in a location query. The 
justification being that in most cases an IP address can be associated 
with a particular country, region and city. Some items of concern in 
this matter:

A server implementing this XEP directly might be able to pull out a 
connected user's IP address without this tag. I assume a component style

implementation does not have this option, or there would be little use 
in re-stating it explicitly in the stanza.

This XEP is of particular interest for mobile applications. Does anyone 
know if the IP-to-location mapping holds true for mobile connections? 
Are handsets assigned an IP by the local carrier where you happen to be 
roaming, or by your home-network? Do mobile operators even use 
location-mappable IP addresses?

As  opposed to cell towers, wifi access points and bluetooth devices, an

ip address can hardly be construed as a beacon in any sense of the word,

i plan to change the nomenclature to simply "reference" from now on.

Any injections/suggestions/comments? If no suggestions to the contrary, 
i will add type "ip" and rename "beacon" to "reference".

As already mentioned i feel more and more that breaking up the generic 
notation and using dedicated tags for each beacon/reference would make 
sense, but as there has not been much opinions in either direction on 
this I'll leave it as mentioned above under the motto "if it ain't 
completely broken, don't fix it more than necessary..."
