My isp only offers a dynamic ip, I figured how to make it static. Is there anything wrong with that? I just fiddled around with my own hardware did not touch their hardware (cablemodem)

There is no possible way you can give yourself a static IP - your ISP controls that.

There is no possible way you can give yourself a static IP - your ISP controls that. Well, I did it, I set the last assigned IP to my router as static, then I changed the dns to a public dns service. I reset the cable modem and even changed the mac addy on the router to test it, and it keeps the ip.

But they can at any time, and there is nothing you can do to prevent it.

They are still able to force a new IP onto your router.

Even if I set the router to static?

Yup, your router doesn't get to choose the IP it gets.

Even if I set the router to static? That just tells YOUR router to assume the IP will stay the same. If your ISP thinks you're using the new number and you router thinks it's supposed to use the old number, things will break. If you have a cable modem (or any other almost-always-on connection), you could wait months before your current IP actually gets recycled and assigned to someone else. Which means everything will work perfectly for months, until you've completely forgotten that you did this, THEN break. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

That's correct. So right now, it's just luck. If your ISP assigns your IP address to someone else, your connection will break. Entering a static IP on your router does two things: 1) Your router will attempt to negotiate that IP address with the other end. 2) Your router will use that IP address no matter what the results of the negotiation. Your ISP will likely give you the IP you asked for if it can. This prevents brief interruptions in connectivity from causing IP address changes. (Most modems/routers will first ask for whatever IP they had last, if they remember it. But they'll accept whatever the ISP offers after that.) However, if someone else has "your" IP address, they won't be able to give it to you and will offer you another IP address. You will reject that IP address, and the link negotiation will fail. Your router will retry the negotiation periodically.

I propose that a mod or cuff cuff "theymos" if they can track my ip record and say when it has changed.

Correction: There are sites that give you a domain name that can be automatically updated by software you run to always point to your dynamic IP. A cable modem is a device that doesn't have it's own network IP (except for a maintenance port), it is a gateway that makes your internal device or network part of the ISP's network. They use DHCP requests from your device (router or directly-connected computer) to assign that particular device an IP address, which will be persistent for various amounts of time depending on the ISP (mine hasn't changed for a year). If you manually specify the same IP address on the device with the same MAC address, it will likely continue to work until the ISP wants you to have a different address or no address (because your IP assignment has expired by you no longer requesting renewals via DHCP), at which point the MAC address of your device will fail to connect through the network regardless of the IP address you assigned to it. If the ISP doesn't do MAC level filtering or IP filtering for unknown devices, then their admins don't know what they are doing. You can pick the IP address of another subscriber and cause network collisions or impersonate them to upload child porn to the FBI (although the network path will likely be logged by something). BTW: if you are getting an address such as 10.0.0.xx or 192.168.xx.xx then your router don't have a real IP address, network address translation (NAT) is being done by your cable modem.

There is no possible way you can give yourself a static IP - your ISP controls that. Well, I did it, I set the last assigned IP to my router as static, then I changed the dns to a public dns service. I reset the cable modem and even changed the mac addy on the router to test it, and it keeps the ip. ISPs are very ununiform when it comes to how they handle IP assignments. You can expect one day that they will assign that IP to someone else and it will stop working for you. You are likely marked as the IPs "last owner" and thus are allowed to take it. That could stop working. Call your ISP and ask about static IPs. You are not doing anything unethical, it is the ISPs responsibility to manage IPs. You might even look directly at the DHCP response and see the expiry time of your IP lease. It may be that their DHCP server grants weeks, months or years to you. That may explain why it is working.

On some ISPs, if you ask for an IP address that is in the set of IP addresses they could assign to you and that IP address isn't currently assigned to someone else, they will give you the IP address you ask for. Most likely your ISP is acting in this way.

Even if I set the router to static? If this happened your computer would stop being able to use the internet. The ISP would reject your packets due to not owning the IP. This is the basis behind a DHCP based internet gateway. The router will obey you but the ISP will not obey the router.
