ip change

Is the NTL ip address assigned to my modem static or is it possible to change it?

Been getting some packet loss from someone in a Mirc channel since they obtained my ip.

I believe it changes monthly. But I think if you turn it of for a period it will reasign a new IP

Hom3r · 23-09-2005, 00:23

Sorry not sure but some one should come along soon and tell how long?

How is your modem connected to your computer as mine was through the usb i have now connected using the ethernet and my ip address change straight away

Ethernet,been looking for my old usb cable but, as usual when i need it i cant find it.

there are two ways to change your IP

first leave your modem off for a few days, its not guaranteed to work though.

second one is changing your NIC card if you use a NIC to plug in your broadband to your computer, if you dont and use USB then use a NIC card and you will have a new IP.

EDIT: turn off your modem and plug the USB cable in, turn back on, you should have a new IP.

True but it also changes if you uninstall your ISP and then reinstall although it doesn't always work

The ip address assigned to your PC is linked to the mac address of the device that is connected. A USB connection will always have a mac address one digit higher than the mac address of the cable modem, whereas an ethernet connection uses a NIC which has it's own mac address. The way to force an ip to change is to change the mac address in one of the following ways:

- switch from usb to ethernet or vice versa
- change network cards
- change the mac address of the NIC; Instructions (for windows):
Go into device manager and then the properties of the network card. In the "advanced" section there is an option to change the network address/ physical address/ mac address. Check the current mac address using ipconfig /all from a command prompt and then increase the mac address by one digit. Reboot everything and you should have a new ip.

You can also change a mac on an Apple Mac that is running 10.1 or higher using terminal, and typing:
sudo ifconfig en0 ether 00:00:00:00:00:00

where en0 is the interface you are using, and the zeros are the mac address that you want to use.

And for all you linux munkehs.... when logged in as root use:

/etc/init.d/networking stop
ifconfig eth0 hw ether 00:00:00:00:00:00
/etc/init.d/networking start

then reboot

Leaving the connection off for a period of time does not guarantee the same ip address, because even if the lease has expired, if the ip address has not been assigned to someone else you will get the same ip back again. Also reinstalling the ntl software will not give a different ip unless you use a different device to connect.

i changed my ip in the nic card properties to a static ip and cloned my mac addy in the router because my router kept changeing my ip every two days and some of my programs stopped working due to it not being able to find my ip i thought ntl look for a mac addy on the nic now
shoot me if i am wrong

Well done on getting it sorted though

The IP address is assigned to the MAC address of your router, not the MAC address of the PC connected to it. Which I think is what you have said, not too sure.
