registry The registry from which the data is taken. For APNIC resources, this will be:
apnic
cc ISO 3166 2-letter code of the organisation to which the allocation or assignment was made.
type Type of Internet number resource represented in this record. One value from the set of defined strings:
{asn,ipv4,ipv6}
start In the case of records of type'ipv4' or 'ipv6' this is the IPv4 or IPv6 'first address' of the range.
In the case of an 16 bit AS number, the format is the integer value in the range: 0 - 65535 In the case of a 32 bit ASN, the value is in the range: 0 - 4294967296 No distinction is drawn between 16 and 32 bit ASN values in the range 0 to 65535.
value In the case of IPv4 address the count of hosts for this range. This count does not have to represent a CIDR range.
In the case of an IPv6 address the value will be the CIDR prefix length from the 'first address' value of <start>. In the case of records of type'asn' the number is the count of AS from this start value.
date Date on this allocation/assignment was made by the RIR in the format: YYYYMMDD
Where the allocation or assignment has been transferred from another registry, this date represents the date of first assignment or allocation as received in from the original RIR.
It is noted that where records do not show a date of first assignment, this can take the 0000/00/00 value.
status Type of allocation from the set:
{allocated, assigned}
This is the allocation or assignment made by the registry producing the file and not any sub-assignment by other agencies.
extensions In future, this may include extra data that is yet to be defined.
