ACSP Suggestion 2014.12: Whois Response for IPv6 Unique Local Addresses fc00::/7
Author: Dani Roseman
Submitted On: 16 June 2014
Please install a ‘whois’ entry for IPv6 Unique Local Addresses fc00::/7
When performing this query:
$ whois -h whois.arin.net fc00::/7
. . . the results are:
No match found for fc00::/7.
However, per http://datatracker.ietf.org/doc/html/rfc4193, that prefix has been identified as “Unique Local” addressing. RIPE has registered it accordingly:
$ whois -h whois.ripe.net fc00::/7 <snip> inet6num: fc00::/7 netname: IANA-BLK descr: Unique Local Addresses (ULAs) country: EU # Country is really world wide org: ORG-IANA1-RIPE admin-c: IANA1-RIPE tech-c: RFC1918-RIPE mnt-by: RIPE-NCC-HM-MNT mnt-lower: RIPE-NCC-HM-MNT remarks: MNTNER added for RIPE NCC DB Group testing 20121024 More specific objects will be created and deleted during this testing over the next few days mnt-lower: aardvark-mnt remarks: This network should never be routed outside an enterprise remarks: See RFC4193 for further information status: ALLOCATED-BY-RIR remarks: This network in not allocated.

Your suggestion to add a an entry into ARIN’s Whois for IPv6 Unique Local Addresses fc00::/7 makes sense, and is something that ARIN will follow up on and complete within the next two weeks.
This suggestion will remain open until implementation is complete.

Thank you again for submitting your suggestion to add a ‘whois’ entry for IPv6 Unique Local Addresses fc00::/7. We are writing to inform you this action has been taken. When you query for an address inside that range you will now see a corresponding whois entry. Note that we currently have a size limitation of /12 for IPv6 netblocks in whois, so the entry appears as 32 separate /12 records, however the entire /7 range is covered by an entry. We will be updating whois to allow IPv6 netblocks larger than /12 in the near future and the /7 will then appear as a single entry.
This suggestion is now closed.
