prefix delegation for IPv6.

[Eddie Lania]

What is the purpose of prefix delegation?
I read the RFC 3633 and do not get it.

Is it correct to assume that on a small LAN, with only one router, there
is no need for delegating several prefixes?
And hence a radvd configured to advertise it's router address is
sufficient?

Regards,

Eddie.
