Yes indeed but I can change IP just by rebooting my modem after an ipconfig release in C prompt if I so wish it You d either have to sock or sit out a block whereas I can either wait as long as the block or not at all depends on how log it is and when I want to edit no website can block visitors effectively if you re savvy enough Even better my ISP can jumps range when you do that so rangeblocks are useless One of life s little bonuses of being anonymous is that IPs are like stars there are billions of them mostly unnamed I guess that s why you favour mandatory registration which explains a lot in terms of your attitude and resentment when IPs edit articles on your watchlist You revert anon edits quicker than my pulse beats
