Static IP addresses

I want to ask some stupid questions. Why don't ISPs automatically set up static IP addresses for the customers? Why does it cost $10-$20 to get a static IP address? If everyone with an internet access device tried to get on the internet at the same time, would that cause some type of IP address shortage?

Yes, that's why IPv6 is right around the corner.

Couple reasons I can think of (and they may or may not be correct):

-Computer defaults to obtaining dynamic IP. Static IP would require the user to configure the device to use the specific IP. Users in general are too stupid to do this.

-A way to increase revenue. Want the convenience of a static IP? You must pay x dollars more!

-Easier to implement. If you have 100k customers would you rather have a computer assign IP addresses for you and reuse that IP for a new customer if the first left? Or would you rather maintain all that yourself?

-Makes it more difficult for a user to run a publically accessible server if the IP changes. ISPs don't want you to have a server. But if you must they want you to pay the premium for a business grade account.

Dynamic IPs from ISPs are somewhat static though. I've had the same IP for the last 8 months. Before that it hadn't changed in 2 and a half years.

Re: Static IP addresses

You can do pseudo-static IP assignments via DHCP. Cable companies have done it for years via the MAC address of the modem. In fact, unless you do something to change it at the server a DHCP address won't change upon renewal. As you noted, they don't change very often unless you are on a PPPoE-type system.

The real reason static IP addresses cost more is because ISPs know those who want one will pay extra for it. The vast majority of customers don't even know what theirs is.

You are generalizing way too much. My Verizon DSL connection changes IP every time the modem is restarted(it logs into PPPoE session, rather than PPPoE software). My TWC connection seems tied to MAC address. If I change the WAN interface or clone a MAC address, I get a new IP. Both companies do offer static IPs.

Not with IPV6......

Even with IPV4, with proper routing and the like, you can trace particular events back to a single system even if they share the same external ip.
