how do you reset your ip address?

Answer 1

why do you want to do that?

remember you ahve two. Inside and Outside

your router .... well routes traffic b/t your Outside and Inside Addresses (more exactly it NATS b/t them)

If you want to reset your local IP then reboot computer and router it should give you a new one... if your outside one you want to change... you might be best to leave your modem unpluged for a few hours or over night. when it turns on it MIGHT have a new address. or call ISP

by the way
Vista does not support the command that was mentioned above... Ipconfig release renew. that is legacy to XP and prior versions of xp will give you a message that you do not have priv to do that

Answer 2

Which ip address?
The external address that is seen on the internet can be static or dynamic. This depends on your service/isp. Typically cable modems and dial-up connections get a dynamic ip that can change on disconnect/reconnect. Although cable modems can also be static as DSL and most other connection types are, which means the only way to change this is to request a change from the ISP and they will be very reluctant to do such a thing without a very good reason.
The only way your machine's IP address will be the same as the external/internet IP is if using dial-up or a cable/dsl modem is directly connected to the PC via USB. This is a bad idea in general and most of the time a router sits between the modem device and the computer, and in some cases the router and modem are a single unit. In this case, the PC usually gets an address from the router, most commonly one that starts with 192.168, such as 192.168.1.222. The number will be based on how the router is setup. This is an internal network IP that only exists on private networks. You could manually setup the machine IP to any address in this range between 2 and 254 (1 is typically used by the router), for example 192.168.1.65, then you would need to setup the other network settings; gw, subnet mask, etc. Resetting the computer will ask the router for a new address, however it will typically be the same one that it had previously since; a) the ip address is reserved for a particular MAC address for a period of time so on a brief disconnect it will be assigned the same number; and b) the router gives out ip's sequentially from a pool that starts with a particular number, so if only one machine is connecting, or if no other machine requests a number in the time that yours is off and the time has passed reserving that number to your MAC address, it will again be assigned the same number.

Now if you're just trying to reset the networking because windows TCP/IP stack went stupid as it tends to do sometimes, just restarting the machine will *usually* take care of that. There are other methods, but the easiest is to just restart the machine.
ADD: I added *usually* above because some spyware / adware / malware can screw up the TCP/IP stack which requires removing the offending software and repairing the damage done (replacing corrupted files, etc.) In this case, any networking functions are normally useless.

Answer 3

If you are hooked to a device that automatically assigns IP addresses, then it can be a little tricky. Routers and switches often come with what's called a Dynamic Host Control Protocol (DHCP) which automatiaclly assigns addresses to the devices connected. Some do it by which port you phsyically connect to, others have no rhyme or reason. That being said, here's something to try:

Open your network status (under Windows XP, this is Start > Settings > Network Connections > Right-Click on your connection > Status), and click "Repair Connection." This will cause Windows to disconnect and reconnect to the device.

Another option is to open the properties of the connection, which can be found here http://www.speed.net/support/ipchange/ (if using XP, use Windows 2000 example)

Answer 4

Do the two, in spite of the undeniable fact that it probable wont artwork besides. once you're assigned an ip handle, you somewhat have a hire on that ip handle, meaning, you've got it till that hire time is up, it somewhat is in many circumstances approximately 7 days. potential biking won't enable you to modify your ip. in case you somewhat need to alter your ip handle, log into your router and alter, or spoof, its mac handle. exchange the mac handle interior the router, after which potential cycle the two instruments. this might exchange your ip handle. Edit: in the journey that your ip is static like one consumer suggested, then it by no ability adjustments. Ever. that's what static ability.

Answer 5

Depends on the connection your isp is giving you. If its Dynamic you just have to disconnect and reconnet and you'll get a different address. If its static you'll always keep the same IP. There's some programs that will launch your web broser and give you a random ip address though but thats kinda useless unless youve been banned from a forum or something and want to access it again.

Answer 6

Are you using static IP address or Dynamic IP? If you are using Static IP, check TCP/IP protocol properties and change it. If your IP is dynamic, you need to access the DHCP server to change your IP. If you doesn't have authentication to access server, you might change you IP address by using MAC addess spoofing software. Freeware are also available in Internet.

Answer 7

Generally you can't unless you're on dialup. Some smaller ISPs you can get a new IP if you renew it via your modems (or routers) admin interface.

Answer 8

in windows xp or vista, go to start, click run, and type: ipconfig /renew

Answer 9

You could contact your ISP.
