The answer depends on the service provider that you use. For example, over here, I believe Verizon uses a dynamic address, and will provide a router. This means that the PC can use an internal (NAT) static or dynamic address, while the router uses a dynamic address.

So if you keep your PC and DSL on (for Verizon), will you still get dynamic IP address ? i.e. do you have to reboot PC or reboot DSL modem device to get a dynamic IP (different from you got last time) ?

I use Verizon too. I just tried different ways but found I got same IP everytime. How often does Verizon change IP for you ?

I tried it again this morning and I got the same IP address. I contacted Verizon one guy didn't know anything about this; another guy said it is still called dynamic IP although I keep getting the same IP address --- he said the reason why I got the same IP was because I set my LAN in some way that enables verizon assign a same IP address all the time, and LAN is beyond their responsibility. I am not sure if he said makes sense..

Any idea from our smart java folks ?

I don't know which DHCP server Verizon is using, but... with the few DHCP servers that I administered...

The DHCP server rarely, if ever, assigns you a different IP address. It keeps track of your MAC address, and tries to assign you the same address as before. I think the only way to get a different address, is to let your current address expire (your router have to be off for the period of the lease).

And there must be more customers than addresses, so that another customer can steal your address. In other words, it probably won't happen because it would be silly for Verizon to not have enough addresses for their customers.
