Update to the IPv4 Registryıs Format and Content
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:
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
