Oh ! Gee ! That's a welcome suggestion. I have two more sets of IPv6 data already nmap'ed over quite a few hours that are in the old grep-unfriendly format. Fortunately, my brute-force workarounds are less time-consuming than the original nmap scans, from which there is no escape. Unfortunately, nmap's avoidance of excessive repetition runs afoul of my use of the simple-to-use LibreOffice Calc in that I'm faced with multiple days of filling in the empty cells between the infrequent asn-query results, which nmap limits to one lookup per CIDR block. Another roadblock is Google's aversion to robots, so my search for "other" IP addresses of multi-addressed PTR's is necessarily a manual task, what with the scores of CIDR blocks filled with identically named PTR's.
