Reverse FNS

Reverse FNS (RFNS) FNS is a subsystem that creates for each free name, closed or open group a specific DNS name (named: name RFNS). This subsystem increases the compatibility of FNS with DNS, and it promotes the use of services associated with a name FNS allowing it to anyone who has not installed the client “FNS Setup”.

The association: nome FNS <-> RFNS name is automatic when creating any name FNS. The resolution of RFNS name is always possible, but it is recommended only if the corresponding name FNS (whether it be a free name, a closed or an open group) It does not point to an existing DNS domain that is different from: * (named: DNS domain of origin); in this case in fact, a name resolution RFNS, It could respond with the IP address of a virtualized service (eg, a virtual web server or a virtual FTP server to which you are DNS domain of origin): the virtualized service would not recognize the name RFNS and resolution would not produce the desired effects.

Examples of FNS names and their names RFNS:

Nome FNS
(installing FNS Setup)
name RFNS
(without installing FNS Setup)

The transformation: nome FNS <-> RFNS name is done by reversing the order of the groups and of free names that make up the name FNS and adding the domain “” at the end.
The RFNS name thus obtained can be solved without installing any client and inherits the same settings of the groups and names free of its name FNS (eg, the write rights or levels of different groups, as well as the distinction between closed groups, open groups and names free).
The part “” (respectively second-level domain: “freenamesystem” e Top Level Domain: “net”) that composes the end of RFNS name is purely complementary addition and for obvious reasons of compatibility with the DNS.
