If you want to know the registry assignments / allocations made to a single entity and be able group together these assignments of address prefixes and ASNs you should retrieve the combined extended stats file from the RIRs (https://www.nro.net/wp-content/uploads/apnic-uploads/delegated-extended) and group together all those entries with a common value in column 8 (except for the entries corresponding to assignments and allocations made by the RIPE NCC, where this information is, unfortunately, not published by them in such a convenient format.)
care to give a decode for the fields in that file? :)
sure, I'll try.
Or: https://www.nro.net/wp-content/uploads/nro-extended-stats-readme5.txt -Hank
for example:
arin|US|asn|32|1|19840924|assigned|658cc9c515b51665f88b7fd1bc213d20|e-stats
Col 1 - RIR name, or 'iana' Col 2 - The country where the entity 'resides' (or 'EU' in some cases), or 'ZZ' for reserved and unassigned blocks Col 3 - 'asn' or 'ipv4' or 'ipv6' Col 4 - The size of the allocation (asn or IPv4) or the prefix length (ipv6) Col 5 - The starting value of the block Col 6 - A date. For some registries this is the date of the original allocation - for others (ARIN) its not so clear precisely what this date signifies (!) Col 7 - Status of the block Col 8 - A hash field of the entity code (mu;ltiple allocations to the same entity have the same code) or null (RIPE NCC, IANA) Col 9 - The source of the record (either "e-stats' where the original source is an extended stats file published by an RIR, or 'iana' if the data is lifted from an IANA registry)
