DHCPv6 Prefix Delegation Clarification

[perl-list]

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. 







Thank you,
