| IP Address Help
I'm having trouble with my IP address and would like to change it. I don't have a router. I tried shutting off my computer and modem over night for a couple weeks straight and still have the same IP address. My ISP is Optimum Online. Will my IP address ever change if the computer is just shut down every single night? Could I go literally years with the same IP address even if I shut down my computer/modem every night, or is the IP address bound to change every few months or so? The longest my modem/computer is off is about 9 hours or so. I just wanted to know if the IP address will change automatically over time if the modem/computer is off every night, or if leaving it off the last several nights didn't work, it may not work for months/years? |

| I'm not at familar with Optimum Online but there is forum here »OptimumOnline
Generally speaking unless you're paying a premium for a static IP, your IP will change eventually.
Is there a polite way to ask 'What happened?"  |

Optimum Online users are provisioned with dynamic IP addresses. They *may* change periodically. There is no way to force a change (although a few people have claimed that leaving the modem off for long periods of time has worked), and there is no prior notice when a change does take place. You could try calling them if you have a legitimate problem (what does "having trouble with my IP address" mean? If you are looking to gain access to some place where your IP address has been banned, forget it), but don't expect it to happen:
(f) Optimum Online: An electronic two way online information and communication service of Cablevision (which includes proprietary products of Optimum Online as well as Internet access) which is delivered over the cable system and accessed by your personal computer via a cable modem. The service is provisioned with a single Dynamic IP address. The address will change periodically and without prior notification.

I think my IP address has changed only twice in six years (not counting moving to new addresses).

You can try this:
Start - Run
"ipconfig /release" and click OK. (Without the quotation marks, and note the space between ipconfig and the /release.)
Start - Run
"ipconfig /renew". (Also a space.)
And this:
Start - Run
"ipconfig /flushdns" to flush the DNS cache.
Then maybe reboot the modem.
It may or may not change it. |

I don't think that will work on OOL, but the OP could try this if he is using a router:
»how can I force my external IP address to renew?

My cable operator assigns an IP address based on the network cards MAC address. If the MAC address remains the same, it might take something like 6-12 months before the IP is changed.
Since I dont have an english language XP, I can only give vaque translated instructions where to find it.
"Go to control panel, network connections, right click connection icon, select properties,the first button in general tab, from the coming new window, the second tab, there is Network Address. By changing it by trial and error you can find working addresses."
Each working one will give you a different IP, works at least for me. Not going to tell what the working addresses are in my puter. You have to find out yourself. All the new IP's will belong still to your ISP's pool.
Keep the original MAC address written down so you can get the internet working back!
In addition some firewalls have rules so tight that you have to reboot for the effect to to be tested. Kerio 2.1.5 and Sygate to my knowledge allow the IP address change on the fly. Depends of course on the ruleset fed to kerio 2.1.5 :P
EDIT
I don't have a router. Maybe in that case what is needed is to change the router's MAC address. |

With Verizon, and previously with Adelphia, I can/could get a new IP address anytime by simply powering down the modem for a few minutes.
But it sounds as though Optimum Online is using what amounts to 'dynamically static' IP addresses. Twice in six years? That's about as 'dynamic' as watching paint dry.
Both good & bad to it, I guess. With a dynamic address though, I sure would want to be able to easily get a new one when I wanted. Doesn't sound like they're making it that easy. |

Call your ISP up make sure you have your mac address ready and your account # then ask them to change your ip address,
If you had a router it could be easyer for you to change it |

Unless you change the MAC address the internet provider sees, it will probably not change anytime soon.
You would have to release the IP address and wait for the ISP to reassign it before it can change passively.
Either physically changing your NIC or using a router and cloning in a new MAC address is the only way to have it change "on-demand".
You can get a decent router practically anywhere, real cheap.
