Hi all, I found a (minor) black list who blocks my new IP. They say to not even try to ask for delisting unless I am the official owner of the IP. They observe that "rwhois/SWIP is normally offered free of charge by most providers". Sounds oldish, doesn't it? RDAP is working well, at least for numbers, and I see no reason to mention rwhois, SWIP is mentioned in a 1993 RFC[*] in the context of a move toward an "X.500 distributed database model". Where are we now? I see ARIN has relatively recent blogs on that.[†] My ISP says that registration is reserved to non-GPON "privileged fiber" whose costs start at around 10x ordinary fares. How much does RIPE charge for registering reassignments? Why isn't it possible for end-user to claim IP "ownership"? If the IP database were dependable, there wouldn't be so many site-verification TXT records in the DNS. I use RDAP to complain about network abuse, and the average response I get is that they passed the complaint to their customer. Some times ISPs make pressure on the customer to fix security leaks, so this seems good. In some other cases, ISPs ignore complaints, whereas the operator might have been interested. Alternatively, complaints might be sent in Cc: to national CERTs, LEAs, AbuseIPDB, and the like. Simple reassignments can be done without changing abuse-c. Does that still imply any responsibility?
