Hi, I mean one thing that has to be considered is that what I think of as the portal UI is only available to LIRs, so on a quick consideration, to me it doesn't really seem to help all that much to add NRTM to it. A limit on how many objects could be monitored wouldn't really make sense imo. I don't think we want to make it complicated and require a new protocol as NRTM is a sort of a standard and not just RIPE makes it available but other IRRs too. I have not thought this through that much but I think the following might be good: - Have a contract with a ToC attached to anyone wanting to use NRTM. - Remove the requirement to be a member of the NCC. So pretty much just a be a member or sign this agreement but with no further changes, that is my idea. I am definitely open to arguments, but this was just what seemed logical to me on a quick thought. - Cynthia On 2019-03-24 01:30, ripedenis--- via db-wg wrote: > Hi All > > I haven't given this any in depth thought yet so it was only my > initial reaction.
