This data call returns address space objects (inetnum, inet6num...) from the RIPE DB (whois) related (exact, more- and less-specific) to the queried resource. Less- and more-specific results are first-level only, further levels would have to be retrieved iteratively.
https://stat.ripe.net/data/address-space-hierarchy/data.<format>?<parameters> 
e.g. https://stat.ripe.net/data/address-space-hierarchy/data.json?resource=193/21
For performance reasons, the data call is limited to 1000 returned object for each more- and less-specific results.
Parameters
| Key | Value | Info | Required |
|---|---|---|---|
| resource | prefix or IP range | The prefix or IP range the address space hierarchy should be returned for. | YES |
Output
Data
| Key | Info |
|---|---|
| exact | A list containing exact matches for the queried resource. |
| more_specific | A list containing first level more specific blocks underneath the queried resource. Some of these may be aggregated according to the 'aggr_levels_below' query parameter. |
| less_specific | A list containing first level less specific (parent) blocks above the queried resource. |
| rir | Name of the RIR where the results are from. Currently this datacall will only respond for resources under RIPE NCC IP space, so this field value will be "ripe". |
| resource | Holds the resource the query was based on |
| query_time | Holds the time the query was based on |
