This message has been sent to several lists. I apologise for duplicates.
IANA has improved the format for the IPv4 Address Space registry. At the same time, the entries that were marked ³Various Registries² have been replaced with references to the Regional Internet Registry (RIR) that provides WHOIS and reverse DNS service for that /8 allocation.
If you want to machine-process the IPv4 registry, the new fields are:
* Prefix * Designation * Date * Whois * Status * Note
where the Date will always be of the form ³YYYY-MM² and the status has the following possible values:
RESERVED, LEGACY, ALLOCATED and UNALLOCATED
/8 allocations that contain legacy assignments in them that are now managed by the RIRs have the text ³Administered by² in the Designation column. Legacy assignments refer to IP address allocations made before the RIR system was established.
Reserved address space held by IANA does not have a date listed.
The registry can be found at:
If you have questions about the structure of the new format, please send e-mail to email@example.com.
