So if I see a MUST in an RFC it does not mean that this bit is required for the protocol to work? That is not how I understand it. I agree with what others have said that for DNS to work all real glue have to be presented. Everything else, including sibling glue is optional and will make the additional section bigger an hence more likely to get truncated. I have no problem with authorities sticking sibling or even out of zone glue in the additional section if they see fit. Resolver will use or ignore that as they see fit and all of that if fine. However requiring authorities to put unnecessary data in the additional section (the sibbling glue) is not something I support. So ong -Ralf ——- Ralf Weber
