Problems changing my i.p address...

This is a really noob question but I need to know how to change my I.P. address. I have a 'dynamic' i.p on my internet plan and I've seen my I.P. has been different a few times but I need to know how to change it when I need to.

At the moment I have a modem connected to a wireless router which is wirelessly connected to my computer.

So the normal, ipconfig > release > renew doesn't work.

I have a Buffalo 'WHR-HP-G300N'. It has something like 500 configurable settings. There definitely should be an option in there somewhere to release my i.p address and give me a new one.

Back on my old broadband back when I needed a username and password to connect to my internet I could just dial a connection on top of my connection that changed my i.p. every time I disconnected and dialled a new one. So I could easily change my i.p. address in just a few seconds..

Now it seems I can't despite me having a Dynamic I.P.

 

You can't directly change your IP address if yours is a dynamic one. Your ISP is assigning this IP to you.

There are some ISPs that offer static IP addresses, but you will need to call them every time you need it changed.

If you're trying to change your address due to banning/spoofing, your options are really only proxies and VPNs.

 

It's not because of either of those things. So what is the point between a dynamic or static then if your ISP dishes both those out for you..?

Why can other people change their I.P. addresses in an instant and I can't seem to...? They have dynamic ones as well.

 

It can be faked, which is what some people do, but unless you did something, there is no reason to do so.


Your renew IP on your router isn't going to do anything. It gets it's IP from the modem (unless it's bridged). You need to reset the modem. You may or may not get a new one, it depends on how often the ISP rotates them.

 

You can guarantee getting a new IP address by changing the MAC address that is associated with your modem. The easiest way to do this is with a router and MAC address cloning. If you have a router hooked up to the modem without MAC address cloning enabled, it is the routers MAC address that is associated with the modem. You can log into your router, enable MAC address cloning, reboot the modem, and viola you have a new DHCP assigned IP address.

The reason this works is because most DHCP servers associate a IP address (which is logical) with a MAC address (which is physical). This association lasts for at least 24 hours after that MAC address is no longer making DHCP requests to the server. This prevents the DHCP server from accidently assigning 2 public IP's to the same MAC address which would have some serious implications regarding routing.

 

Ok so I found this:



Looks like it's pretty much what I needed. I also did a google and read up on Mac-Cloning. I almost completely overlooked this part of my router.

However this is just on my 'router' am I going to need to refresh the MAC of my modem? I can't connect to my modem through my computer because my computer is connected to my router... I guess I'll have to disconnect from the router and manually connect through Ethernet to my modem..? Ugh that's really troublesome, but I guess it's better than leaving the modem and router off overnight.

Even after all this (trying with the router) I am unable to change my I.P... I still haven't got a new one even with the Mac-Cloning on my router. I've changed to multiple things.

 

Its the WAN IP that needs to be changed, not the IP that is on your PC. If you enabled MAC Address Cloning on the router, you got a new WAN IP. No ifs and or buts about it.

There is absolutely nothing that needs to be done on the modem and no reason why you would need to log into it. You can still log into the modem even if your PC is connected to the router, that makes no difference.

If you did not get a new IP Address after enabling MAC Address Cloning, then your WAN IP is not being assigned through DHCP but is Static instead.

 

It's not static... it's dynamic. Look:



So what am I supposed to do now? I've read in a lot of other places on the internet that you need to also set up cloning on the modem because that is what is directly connected to the ISP, not the router.

Should I change the MAC on my wireless card as well?

I also have another place to change another I.P. but it's local:



I know I'm so close to being able to do this...

 

First, I'm going to respond to the statement I highlighted above. This statement is not fully correct. The modem is not connected to the Internet, it is connected to a Subnet that has been setup by the ISP to allow the modem to gather information you need for Internet access, including a public IP Address, a DNS Address, and a Default Gateway. It is the device that connects to the modem that is connected to the Internet, in your case the router. Like I mentioned before, if your ISP assigns your IP Address with a DHCP server all you have to do is enable MAC Address cloning on your router and you will get a new PUBLIC IP Address. If your ISP gave you a Static IP Address, the only way to change it is contacting your ISP.

READ THIS FIRST then READ THIS. When you're done with those, READ THIS TOO. After you understand the difference between a public WAN IP and a private LAN IP you can READ THIS LAST to understand how they can work together to allow Internet access on a Private Network.

After you have read and understand those articles, please come back and ask your question again, I have most likely already answered it.

If you want to change your PRIVATE IP in Windows, HERE is how.

 

Thanks for that freesafety13. I read those wiki articles you linked to quickly but really I already knew just about everything in those articles.

I used to be able to change my external address as often as I liked by dialling another connection on top of my existing connection. This was when I was using Windows XP with a username and password, back when I was issued a username and password to log into my broadband internet connection.

These days I only seem to get one external ip.

It IS Dynamic. That much is known.

There is no option on the modem to set up 'MAC Address Cloning'. Only on the router. Something tells me that even though I have MAC Address Cloning on the router set up that because it isn't set up on the modem that it wont work...

I have cloning set up on my router:



But my external address (my dynamic outgoing address) is still the same..

What should I do now..?

 

You CAN'T change your external IP! ITS ASSIGNED BY YOUR ISP!

 

Oh? So what the is MAC Address Cloning for then..? Pretty much everything I read about Mac Cloning is a lie then eh? That makes a lot of liars writing a lot of lying articles on the web.

Also, what's the point of ISPs being able to assign you Dynamic or Static I.P. addresses if they're both the same rofl?

Lastly, if I can't change my I.P. address, why.. about 9 months ago could I dial up a new connection over my old one and get an entirely new I.P. address eh?

 

MAC address cloning has nothing to do with your external IP.
Back in the day most of cable operators used this as a method of authentication. Only one device worked when connected to the net- other wouldn't even obtain an IP.
So MAC cloning is meant to copy MAC from the device that can be authenticated and use it on the router so the router would look like a device that can be authenticated.

There's a lot of confusion in this thread- most thing discussed including MACs and DHCP have nothing to do with an issue in question.

Are those configuration screenshots from a router or a modem?
What type of connection is it- ADSL or cable?
What modem do you have?
Can you log in to the modem?

 

I can log into everything. It's all my infrastructure so I can access it any time I want.

I have a Telewell TW-EA501 Modem
and a
Buffalo WHR-HP-G300N Router

It's ADSL, not cable.

The screenshots are ALL from the router. I haven't posted any of the modem.

Thanks a lot for your reply downloads

 

OK- so disregard the router and go to the modem now.
I'm assuming the modem isn't in bridge mode- you would have known it it was.
The modem itself is responsible for obtaining and releasing external IP so you should be interested in its config panel.

EDIT: Unfortunately it's also possible that your modem obtains a private IP and your Internet facing IP isn't really your IP but an IP of a proxy server of your ISP. We'll see if that's the case later.

 

As for the Modem. It's not bridged, no need.

What options am I looking for with the modem? Same deal, MAC Address cloning etc? My modem doesn't have half the amount of options my router does unfortunately :/

I understand the issue with DHCP and my ISP not releasing my I.P. address if I want it to. I haven't witnessed my I.P. change ever whilst using this ISP.. so maybe they wont rotate it at all but it is Dynamic if I can get it to rotate I would be eternally grateful...

Thanks again for sticking in this far. Throw me a list of things I should look for and I'll get onto it. Hopefully I might me able to work the rest out on my own.

 

There should be "release" and "renew" buttons on a status page of your modem.
Something looking more or less like this.
