[TelstraClear] Telstra Static or Not IP?

sbnmiky, you appear to be presenting a solution that is masquerading as a problem.

You have asked the question: "Which ISPs offer dynamic IP addresses?"

Other respondents have asked why you want this. In other words, they are asking what you problem is. What is the problem that you are trying to fix with dynamic IP addresses?

If you can tell us what that problem is, we may well be able to help you.

Please note though:

Static IPs don't make you more vulnerable to hackers.

If you look at your traffic, on any sort of connection---dial up, static IP broadband, dynamic IP broadband---you will see the Bad Guys come calling within a few seconds. Fire up a tcpdump and see the port scans incoming. They are more or less constant. If you have an an unsecured system an intrusion will be attempted. This is not targeted at your particular IP, this is just a gratuitous payload of doom sent out to the world at random.

Dynamic IPs usually aren't.

The default action for most DHCP and PPP servers out of the box is to cache the IP address and serve you the same one it gave you last time. That is, even if you refresh the DHCP lease you will almost certainly get the same IP address back. The ISP actually has to make an effort to give you a different IP address, so they probably won't. The address will only change if the network topology changes or the server reboots (probably not even then) or the ISP almost runs out of addresses---in which everyone has much worse problems to worry about.

Your ISP responds to Abuse

abuse@ispname.example.com that is. If you do something that really annoys someone, they may fire up the LOIC and DDoS your ISP off the planet---which removes you and rather a lot of other people as well. But actually most people will probably fire off an aggrieved email to their ISP. Which, if you have been naughty, will most probably end up at your ISP's "abuse" email address. Your ISP does know who you are, static or dynamic IP. If they find you've been clueless, they'll patiently explain. If they find you've been evil, that would be against the terms and condtions. Bye bye.

NCIS is not realistic

Well, not with respect to anything to do with the Internet or encryption.

To recap. You probably don't need a dynamic IP address. You probably don't need a static IP address either. However, if you explain what problem you are trying to solve, the collective wisdom of Geekzone can probably answer it for you.
