My ISP is using dynamic IP addresses, now I have problems with my IP (it seems to be blocked somewhere) and want it to be changed. My ISP says to me that they can't assign a new IP for me, can that be true? I have powered off my cable modem for over 10 hours but when I turn it on I get the same IP address.

Have you tried releasing and renewing your IP address on your computer or router? – Alvin Wong Apr 23 '13 at 14:58
Does no good for his IP with the ISP. – AthomSfere Apr 23 '13 at 15:01
Are you sure it's a Dynamic IP Address? – KronoS Apr 23 '13 at 16:59
@slhck - Any idea why this question was closed as off-topic? Isn't a modem or perhaps a router considered computer hardware? – Kevin Fegan Apr 24 '13 at 0:49
@Pekka Tiira - you didn't mention who your ISP is, and if your setup includes a router. If you use a router, you can probably get a new IP address by spoofing the MAC address in your router. That is, to copy the MAC address from your PC into your router. – Kevin Fegan Apr 24 '13 at 0:55

Your ISP wants it both ways. They reserve the right to have your IP address change dynamically (as new customers are added or their network is reconfigured). They also don't want to give you a static IP. And they don't want to support manually changing your IP due to it being a hassle for them.

You might be able to use a proxy (something like TOR) to access the site but probably better to contact the site owner and resolve what got you banned.

I wouldn't hold much hope on your ISP changing your address for you.

Thanks for the answer, so I must find away myself to get a new IP-address. I will release the IP-address and power off the modem/router for a week :D perhaps that will do the trick? – Pekka Tiira Apr 23 '13 at 15:20
You aren't going to get a new IP, you are going to bypass the site's filtering. This doesn't actually resolve anything its getting around. It also doesn't really sound like your blocked from anything per your reponse to me below – AthomSfere Apr 23 '13 at 15:21
I think you are better served trying to solve the root problem. Can you access the site from another computer (or something like a phone)? – Brad Patton Apr 23 '13 at 15:22
Yes I can access the site if I use my wife's phone (other ISP) or if I use other cable modem/router because then I get another IP-address. – Pekka Tiira Apr 23 '13 at 15:27
Please add all relevant information where it belongs, in the question above. Be thorough so we can have the required information and go from there. – AthomSfere Apr 23 '13 at 15:31

Yes, it could be true. From the standpoint that the impact of forcing the entire network to re-lease its IPs could outweigh the benefit of fixing your issues.

As for it being blocked, they don't know for a fact that you did not get banned from a forum, or blocked from a website for doing things you shouldn't. It really is up to you to find a way to contact any sites that are blocking you and attempt to get the ban released.

Well as far as I know I'm not banned anywhere and the only website I can't access is my own site! And I'm not blocked there at least that is what have been told to me. – Pekka Tiira Apr 23 '13 at 15:10
Internal site? Where is this site? There really should be alot more information in your question then. What error are you getting? Why would you think you are blocked? etc. etc. etc.. – AthomSfere Apr 23 '13 at 15:20
What do you mean by "I can't access my own website"? – Sacha K Apr 23 '13 at 15:21
If I try to get my home page I get "timed out" error, I can't use cPanel, use my email, ftp is not working. – Pekka Tiira Apr 23 '13 at 15:30
Check if the home page is accessible by – Sacha K Apr 23 '13 at 15:44

Of course they can - well, not the first level support guys you are speaking to - but they don't want to.

Why would they want to have people banned from whatever forum calling them the whole day to get their IP changed? Also what would they do with all the IP addresses banned all over the place?

He's asking "My ISP says to me that they can't assign a new IP for me, can that be true?", so actually it is. – Sacha K Apr 23 '13 at 16:04
So now you remove your comment saying "It's not an answer to the question." and you downvote? Really nice of you. – Sacha K Apr 23 '13 at 16:28
I have not removed anything or downvoted! – Pekka Tiira Apr 23 '13 at 17:09
I didn't mean you, sorry it wasn't clear. Some guy did, don't remember his nick. – Sacha K Apr 23 '13 at 18:32
@user2210761 - "so actually it is". Just because ISP said can't doesn't mean they actually can't. Most likely they can but just don't want to. – Kevin Fegan Apr 24 '13 at 0:45
