Subject: Convergence can be done within a DNS


Assume you want to translate a phone number to an IP address (chould it be IPv4 or IPv6), this can already be done using DNS:
Example: you want to translate a phone number in France, say:
You could think it can be done by requesting a domain name like:
(This assumes that phone is a TLD, in which each international phone code is registered and operated as a sub-TLD, and then the number is solved appropriately within that country registry.)
However there are issues, such that renumbering schemes (how many digits have to be searched ?)
Another solution is to use the reversed phone number and cutting phone number in individual digits:
That way, you do not have to parse the phone number to find the minimum set of digits that successfully resolves a domain name, and the numering plan can be changed by distributing sub-DNS in each country. Because this domain name is algorithmicly implement, it lacks of readability. So each country could decide on the usual format to give to phone numbers so that they can be easily parsed.
Requesting the DNS could then return additional information, such that the kind of information that can be returned by reversed phone number searchs, however there are some privacy issues that should restrict the information returned by DNS requests.

What I mean here, is that converging numbering plans to IP is not necessary, because this process can be automated within dynamic DNS servers operated by country phone registries and ITU.
