Oh, it's not just ISPs - it's all across the board: DNS services (especially the smaller ones, but that's understandable), tools... weird inconsitencies in tools, too: some get an extra parameter (-4/-6), others get an extra sister program (ping6, nslookup6...), and then there are all the services for "what is my ip": nearly all give only an IPv4 address, and no clue even if they have an IPv6 version - and there are very few of those. #ipv4 #ipv6 #tools
