RTBH IPv6

RFC6666 allocates 0100::/64 for use as a range of IPv6 discard prefixes. Only a single /128 needs to be allocated even though the below example uses the entire /64. A /128 is preferred as this allows other IPs in the range to be allocated for other filtering purposes. The RFC6666 range is unique for this purpose. The IPv4 range below is from RFC5737 which is not ideal as this range is for documentation purposes, not for live operational use. Equally RFC1918 space is meant for private use and may genuinely be seen inside a routing table so using RFC1918 and/or RFC5737 space maybe misleading.
