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.

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..."
