Hello Ronald,
Thanks for bringing this up. I have looked into it and would like to
provide you with an explanation on why these two /24s are recorded in the APNIC
registry.
The mentioned two /24s belong to APNIC. We nominated them to IANA in the
RFC 5737 "IPv4 Address Blocks Reserved for Documentation" in 2010.
https://www.rfc-editor.org/rfc/rfc5737.html
You can see the following message in the "Acknowledgments" section of the
RFC5737.
"The authors would like to offer a special note of thanks to APNIC, which
nominated 198.51.100.0/24 and 203.0.113.0/24 for this purpose."
We were asked by IANA to register the following objects in the APNIC Whois
database at that time for public information.

Later, the NRO generated the daily stats file to combine all RIR data and IANA
data to provide an overview of the status of all number resources. We knew
there would be a conflict between APNIC data and IANA data regarding these
ranges. We chose the IANA data as the higher level information in the NRO stats
file.
iana|ZZ|ipv4|198.51.100.0|256|20090714|reserved|ietf|iana
iana|ZZ|ipv4|203.0.113.0|256|20090714|reserved|ietf|iana
The information in the APNIC registry is to provide further details to the
public. We have the same message "those ranges are reserved for documentation",
just at different levels.
I would like to use this opportunity to remind others that there are
special resource ranges for documentation guided by RFCs.
IPv4: 192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24 (RFC5737)
IPv6: 2001:DB8::/32 (RFC3849)
ASN: 64496 – 64511 (16-bit, 2-byte), 65536 – 65551 (32-bit, 4-byte)
(RFC5398)
Please feel free to use them as examples when you write documents or do
presentations. You don't need to use private IP or someone's IP as an example 😊
Kind regards,
Guangliang

Subject: [apnic-talk] RFC reserved IP blocks in the APNIC WHOIS data base
APNIC Hostmaster,
The following two IP address blocks are reserved as per RFC 5737, Section 3:
198.51.100.0/24
203.0.113.0/24
As per RFC 5737, Section 3, these two blocks do not belong to any specific or
particular Regional Internet Registry, nor should they be assigned to any
individual or particular resource member of any particular RIR. Both blocks
are effectively reserved by IANA, based on RFC 5737, and that fact is reflected
in the NRO's daily stats file, where these blocks are quite clearly assigned to
and associated with
IANA:
iana|ZZ|ipv4|198.51.100.0|256|20090714|reserved|ietf|iana
iana|ZZ|ipv4|203.0.113.0|256|20090714|reserved|ietf|iana
Nontheless, these two blocks are also incorrectly mentioned in APNIC's own
daily stats file, where they are incorrectly represented as allocations under
the administration of APNIC:
apnic||ipv4|198.51.100.0|256||reserved|
apnic||ipv4|203.0.113.0|256||reserved|
Please remove all references to these two RFC-reserved IPv4 address blocks from
both the APNIC WHOIS data base and also from the APNIC daily stats file. All
such mentions of either block in APNIC-specific data bases or data files are
invalid and are in direct conflict with NRO/IANA supplied information as noted
above.
Regards,
rfg
