> I do not believe there needs to be special wording for mobile Or for any other specific deployment for that matter. The reason I mentioned cable is because many popular operating system-based hosts as well as specific devices have to be able to operate in a cable environment and the operational reality is that it is a MUST for all of them. However, since there are other, closed, controlled environments where DHCPv6 may not be necessary, SHOULD is the perfect level to cover all of the deployment environments. SHOULD means that you have to follow it unless you have a good case why not (see RFC 2119 below):
3. SHOULD This word, or the adjective "RECOMMENDED", mean that there may exist valid reasons in particular circumstances to ignore a particular item, but the full implications must be understood and carefully weighed before choosing a different course - Wes
