Hello, I started working on IPv6 and some points arent clear. I hope I can get a satisfying answer from you. My firm is currently a LIR but when we want to implement IPv6, shall we become a TLA or sub-TLA? What is the difference between these two? As far as I read, LIRs will be sub-TLA's... Am I wrong? Is there a document explaning these procedures? Best regards Okan
