Fry I did a couple quick RADB queries, and I find no object for as AS30309. In addition there are no objects for the VISI-assigned blocks you mentioned, even with a shorter prefix length. I would strongly recommend a visit to WWW.ALTDB.NET if you already know how to update an IRRd database via email templates; or if not, pay your $500 to MERIT and use WWW.RADB.NET instead. Personally, I have used both ALTDB and RADB, and while it's obvious that "you get what you pay for", and no one should complain if they don't like the free ALTDB service, I have been very pleased with MERIT's responsiveness. -- Jeff S Wheeler
