Theoretically fine, but in combination with autoconfig of links, the domain names are also likely to be meaningless and changing, which means service discovery becomes a "must" for all homenet nodes. And there's the possibility of difficult to debug name clashes as "myphone" or "mygamestation" moves between links. > does a name really have any meaning without a service associated with it? > URLs have meaning (rfc1738). It's going to be tough to know when your browser (connecting from off-net) can cache http://myphone.building1.isp1.com or not. Cookie handling too (keyed on URL, which is hard linked to hostname, which will change when the phone moves to http://myphone.building2.isp1.com).
Or is there some magic to handle this that scales to the whole Internet? At least if just the IPv6 address changed we'd only have to deal with caching hostname -> IPv6 addresses lookups. > let us assume that we don't want anyone to remember these names. the > UI will present a list > of available services, given where you are. > Right, but the FQDN changes every time a device moves, not just the address, which either means large amounts of service discovery traffic (like Appletalk ZIP/NBP + "the Finder" which had huge scaling issues), or large amounts of update traffic plus potential caching issues of anything linked to URL (and in turn to hostname). > in that sense I really don't care what the domain name for my local > link or site is either. > internally I don't use them, for access into my home when I'm outside > I need to type in the externally visible > domain into my service discovery domain registry once. > cheers, > Ole > Ray Hunter <mailto:[email protected]> > 27 February 2013 08:35 > >From the quoted draft: "for the purposes of this document, assume that > each link has its own unique Unicast DNS domain name", > which I don't think is acceptable in Homenet.
