I also said that I had comments in section 6.

The comment relates to sections a and b of item 3 of the registration template - the prefix size.

The lack of guidance on specific prefix allocations in both the accompanying eid-block draft and this draft probably should be addressed. What we want is a balance between ease of access and the lack of imposition bureaucratic registry evaluation procedures and some statement of the expectation of restraint to allow all potential experimenters access to a registration in this block. 

One possible approach would be to state a default allocation size, and might I suggest that a /56 is an appropriate balance between utility and convenience and the considerations of the initial scale of this experiment. If the registrant is seeking a default size allocation (or smaller) then the template should note that no "rationale" would be necessary.

Another option (which I prefer) is to state that it is possible to request allocations of between a /64 to a /48, and that while the rationale would not be formally assessed by the registry, any allocation of larger than a /56 would require a rationale text, and this text would be part of the published registration. i.e. "no questions asked and no explanations given for a registration of a prefix of a /64 through to a /56, and an explanation would need to be provided for larger prefixes, and this explanation would be published (i.e. the justification becomes a justification to the other participants in the experiment as to why this particular participant believes that they require a larger prefix, rather than a justification to the registry operator) This would mean that the registry function is kept simple, presumably cheap (i.e. free) and accessible to experimenters of most shapes and sizes.


I'm not sure that the experiment details (section 4) are necessarily part of the registration process. 

here's an amended section 6 that incorporates these comments.



EID Prefix Registration template

Note that all details in this registration become part of the registry, and will be published in the LISP EID Prefix Registry

 1.  Organization (In case of individuals requesting an EID prefix
       this section can be left blank)

       (a)  Organization Name

       (b)  Organization Address

       (c)  Organization Phone

   2.  Contact Person (Mandatory)

       (a)  Name

       (b)  Address

       (c)  Phone

       (d)  Email

   3.  EID Prefix Request (Mandatory)

       (a)  Prefix Size

       (b)  Prefix Size Rationale

            Note that Prefixes from a /64 to a /48 may be registered.
            No rationale text is required for prefix sizes up to and including a
            /56. The rationale text will be part of the public registry of
            EID Prefixes.

            Note that the registration is for a 12 month duration, and must be
            renewed at the end of this period.
         
            Note that the registration will cease upon termination of the
            experimental LISP EID block allocation.. 
             
   4.  Reverse DNS Servers (Optional)

       (a)  Name server name:

       (b)  Name server address:

       (c)  Name server name:

       (d)  Name server address:

       (Repeat as necessary)



thanks,
