My ip address need reset

Are you talking about Firewall on Windows or on Router or you have a another firewall?

To reset routers Ip address just reset your router to default settings.
But doing that will no solve anything.
If you mean changing your public IP address then switch of your router and keep it switched off for sometime.
Once you switch it on it should have new ip address.

OK. You need to reset the modem to renew ip address from the current one.You can't reset the ip address using the router reset method.So reset or switch off the modem and then switch on it.Then new dynamic ip address will assign will be generate for your connection.Check ip address using the site Ip-Details.com before and after resetting modem...I hope you will get the answer by my reply.

You can get your Ip address by reset your modem or contact your ISP (Internet Service Provider). If it is no so or they fail to provide the IP address to you, then you can get your ip address from the site Ip-Details.com

If you reset the modem and ip address will not change and remains same hence it is static ip address.If you reset the modem and the ip address change ,it is dynamic ip address.
You can get the Ip address from your internet service provider.you can check the ip address using the site Ip-details.com .

Reset your router back to it's factory settings by holding the reset button for about 5 seconds. I have provided a list of the most popular router brands. If it does not work you may need to google what your specific model's default IP address/default username/default passwords are, for example search for "Encore ENHWI-2AN3 default IP address" The default login info can change, it can depend on where you obtained your router. If you purchased it yourself from a store then the standard defaults should work. If you obtained your router from your Internet Provider you may need to contact your service provider. It also may depend whether it's an old or new model router as well. And you may need to press and hold the reset button on your router several times before it actually clears. Make sure you have a wired connection then once you have accessed your router simply run the Setup Wizard. Set your SSID as something you'll remember like "Mavericks Network" and your Password can be something like your phone number for example 3109876543

I hope this helps

Hello,

If you lose the IP address you can reset the network card.

Since the machine no longer has an IP address, you MUST be connected with a network cable.

1. Turn the power off
2. Press and hold the "go" button (the blue one on the front)
3. While holding the Go button, turn the power back on.
4. Keep holding the Go button until all 4 lights are on.
5. Release the "Go" button and press it 7 times quickly.

This will reset the network card and you should get a proper wired LAN IP address.

Thanks,

Pat

Just unplug the router for 10 seconds and plug back in.

Start->Settings->Control Panel. Double click in Internet Options.

On the Connections tab, click on Never Dial a Connection. While you're there, click on LAN settings. Automatically detect settings should be checked, but normally nothing else should be checked.

If this doesn't help, you may need to rebuild the stack:
Start, Run, CMD to open a command prompt.

Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

Reboot the machine
