Renumbering is *NOT* simple and *CAN't* be automated (no remote company will allow you full automatic access to change things in their setup, think firewall rules for instance...) Another example. My company laptop has a VPN client which has two IPv4 addresses in for the main and fallback VPN login servers. Even if there are systems in place for updating these settings when I reboot my laptop, that won't prevent helpdesk calls. For instance, it is common for people to put laptops to sleep without logging out. It may be a week or two between logins. If the network is renumbered, suddenly the VPN login service fails and remote users have to call a helpdesk to find out the new IP addresses. Processing a helpdesk call costs money and downtime due to lack of network access also costs money. It is difficult to foresee these kinds of costs.
really bad example, you never have a 1 or 2 weeks periode (planned time) to renumber, you plan it over monthss to make sure things like you describe don't happen. Good planing avoid alot of issues.. and for the rest of your mail, why can't we all stop thinking in terms of IP addresses and start thinking in terms of hostnames? -- ------------------------------ Roger Jorgensen | roger@jorgensen.no | - IPv6 is The Key! -------------------------------------------------------
