To clarify, the time horizons in policy depend on the nature of the request. ISPs are currently limited to 3 months for IPv4. End users can get 12 months IPv4. ISPs or end users can get up to 24 months IPv4 through the transfer process. IPv6 does not have a clearly defined time horizon and long-term (~5 years) planning is recommended when preparing an IPv6 request. Owen
