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.
