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.
