Subject: IPv6 sub-TLAs Date: Wed, 09 Dec 1998 From: Brian E Carpenter To: email@example.com
The IAB delegated the IPv6 address space to IANA via RFC 1881, and its format is now defined in various RFCs.
The Regional IP Registries (RIRs) are planning to start IPv6 assignments in the first quarter of 1999, to meet the requests they have received from ISPs who are planning production IPv6 service. In order to do this, the RIRs each need an initial set of Sub-TLA blocks to assign. The long term guidelines for this remain to be determined. However, in order to meet the 1Q1999 plan, an immediate initial delegation is required. We request that you make the following delegations.
FP = 001 TLA ID = 0x0001 Sub-TLA IDs delegated as follows: 0 0000 01XX XXXX 0x0040 - 0x007F APNIC 0 0000 10XX XXXX 0x0080 - 0x00BF ARIN 0 0000 11XX XXXX 0x00C0 - 0x00FF RIPE-NCC
