> The man page (man 5 dhcpd.conf) states the following regarding prefix
> delegation:

> The prefix6 statement

> prefix6 low-address high-address / bits;

> The prefix6 is the range6 equivalent for Prefix Delegation (RFC
> 3633). Prefixes of bits length are assigned between low-address and
> high-address.

> Any IPv6 prefixes given to static entries (hosts) with fixed-prefix6
> are excluded from the prefix6.

> This statement is currently global but it should have a
> shared-network scope.

> My specific question is in regards to the final statement. Does this
> mean that the prefix6 statement can currently be confined to a
> shared-network scope but DHCP will not barf if it is in a global
> position, or that it will be global in scope even if placed inside a
> shared-network scope?

> The reason I ask, is that if it is global even if in a specific
> shared-network statement, invalid networks could be delegated to
> clients on completely separate physical networks in our
> implementation.
