On 1 October, APNIC introduced a special type of inet[6]num (that is, either an
inetnum or an inet6num) record, called a whois stub record, into the APNIC Whois
Database. It aims to fill in a few gaps in the data and improve query results.
When APNIC receives IP resources from IANA, corresponding inet[6]num records are
created in the APNIC Whois Database and subsequent delegations to account
holders from these resources trigger the creation of new inet[6]num records,
having the former record as a parent.
Previously, when those delegations were transferred to other regions (different
RIRs), the corresponding inet[6]num records were removed. This meant that when a
user queried for these delegations, whois would return their parent block since
it would be the most relevant result available in the database. This response
would lead clients to inadvertently interpret that the resources are still held
by APNIC.
With the introduction of whois stub records, these queries will now return the
best information available in our registry. Queries for these blocks will now
return an inet[6]num record stating that the block has been transferred to
another region. Similarly, queries for blocks that were transferred from other
regions and were subsequently deallocated will also result in a stub record.
The following inetnum object is an example of a stub record for a block that was
transferred to another region:
inetnum: 43.225.112.0 - 43.225.115.255
netname: STUB-43-225-112SLASH22
descr: Transferred to the RIPE region on 2018-12-04T08:38:56Z.
country: ZZ
admin-c: STUB-AP
tech-c: STUB-AP
status: ALLOCATED PORTABLE
mnt-by: APNIC-STUB
mnt-irt: IRT-STUB-AP
last-modified: 2019-09-30T00:15:22Z

Once the resource has been transferred out of APNIC’s region, APNIC can’t assert
its economy, so the country code ‘ZZ’ is used to denote that the country is no
longer known.
The description field contains the region to which the resource was transferred.
With this information, users may query the whois server of the transfer
recipient’s region and obtain the most up-to-date registry record for the
resource.
If you would like your queries to be automatically redirected for resources
outside APNIC’s region, please consider using RDAP (more details on
https://www.apnic.net/about-apnic/whois_search/about/rdap/ ). Automatic
redirection is just one of the many advantages of using RDAP over whois.
If you still want to use whois, JWhois also provides automatic redirection and
can be accessed by setting your client to use jwhois.apnic.net as host.
Any feedback on this new feature is welcome.
