Fair enough.. having now read bad apple's reply to you /properly/ you're both right and although there are still some customers with dialup modems they are by far in the minority. Also despite DSL /technically/ being a dialup connection to the network, I think in practice most - if not all - people have a router at home which only has to reestablish a connection if it's turned off.On Fri, Jul 5, 2013 at 10:27 PM, Julian Hall wrote:It could be simply that it would be more expensive for them. Say you had 2 million customers all with static IPs, you'd have to buy a big enough block of IPs so they could have one each. If on the other hand you knew from servers logs etc that the most you'd ever had online at the same time was 500,000 you could get away with a block of say 600,000 to give yourself a bit of leeway and save on the big block expense.This would be a valid argument, if it weren't for the fact that - as bad apple has pointed out - most people are online most of the time. So out of your 2m customers, you'd have 1.8m online most of the time and with a bit of leeway, you'll end up having to buy a block of 2m addresses One advantage with dynamic IP addresses (apart from their ability to 'solve' problems) is that it makes mergers or take-overs easier: you can simply redistribute the new pool of addresses in a more efficient way.
