Section 3 says:
+-----------------------------------------+-------------------------+ | Interface Identifier Range | Description | +-----------------------------------------+-------------------------+ | 0000:0000:0000:0000 | Subnet-Router Anycast | | | [RFC4291] | | | | | FDFF:FFFF:FFFF:FF80-FDFF:FFFF:FFFF:FFFF | Reserved Subnet Anycast | | | Addresses[RFC2526] | +-----------------------------------------+-------------------------+ Table 1: Current Assignments
It should say:
+-----------------------------------------+-------------------------+ | Interface Identifier Range | Description | +-----------------------------------------+-------------------------+ | 0000:0000:0000:0000 | Subnet-Router Anycast | | | [RFC4291] | | | | | FDFF:FFFF:FFFF:FF80-FDFF:FFFF:FFFF:FFFF | Reserved Subnet Anycast | | FFFF:FFFF:FFFF:FF80-FFFF:FFFF:FFFF:FFFF | Addresses[RFC2526] | +-----------------------------------------+-------------------------+ Table 1: Current Assignments
Notes:
Both these ranges are in fact reserved by Section 2 of RFC2526. Under current recommendations [RFC7217] the FDFF range is no longer recommended for routine use, and the FFFF range is equally likely to occur in a pseudo-random 64-bit IID. Credit to Kerry Lynn for pointing this out.
