What is the Hop Limit that a Solicit should contain in the IPv6 header?

(The ISC and a Cisco client set it at 255, whereas odhcp6c client at 1.
  The dst address is a ff02.
  The ND link messaging uses Hop Limit 255.)

Is IA_NA with empty fields a valid option in a Prefix Delegation
Solicit, or must IA_NA be absent altogether? (the intention is to only
request the Prefix, because the address comes from RA).

Is ORO with empty fields illegal in a Prefix Delegation Solicit?  (the
intention is to get the DNS server from RA, but some client puts an
empty ORO there).

Is it ok to use a GUA in the src address of a Solicit Prefix Delegation?
  Is the GUA mandatory, or could LL do it as well? (some server seems to
require it to be a GUA).

> Protocol for IPv6 (DHCPv6): an extensible mechanism for configuring
> nodes with network configuration parameters, IP addresses, and
> prefixes. Parameters can be provided statelessly, or in combination
> with stateful assignment of one or more IPv6 addresses and/or IPv6 
> prefixes.  DHCPv6 can operate either in place of or in addition to 
> stateless address autoconfiguration (SLAAC).

> This document updates the text from RFC3315, the original DHCPv6 
> specification, and incorporates prefix delegation (RFC3633), 
> stateless DHCPv6 (RFC3736), an option to specify an upper bound for 
> how long a client should wait before refreshing information 
> (RFC4242), a mechanism for throttling DHCPv6 clients when DHCPv6 
> service is not available (RFC7083), and clarifies the interactions 
> between modes of operation (RFC7550).  As such, this document 
> obsoletes RFC3315, RFC3633, RFC3736, RFC4242, RFC7083, and RFC7550.
