Re: [apnic-talk] RFC reserved IP blocks in the APNIC WHOIS data base
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
