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 =B3Various Registries=B2 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 =B3YYYY-MM=B2 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 =B3Administered by=B2 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:
http://www.iana.org/assignments/ipv4-address-space
If you have questions about the structure of the new format, please send
e-mail to iana@iana.org.
Kind regards,
Leo Vegoda
