Does IP changes with browsers?

be careful the simply change of browser not change the IP address...

no, IP remain same for any browser. IP is related to your computer system and internet connection. it has no relation with browser.

Unless you use different browsers with different proxy servers configured, no. Closing a browser and reopening it would NOT change your IP address. If you have a dymanic IP address provided by your ISP, it usually changes only when your turn off your modem. It doesn't have anything to do with the browser at all.

no, the ip is something that shows even the adress home to the fbi for example, like that's how they caught some hackers so it doesn't change from computers and specially not with browsers i once did neobux in this pc and then as some hours had pass by i tryed in the other pc as i was there anyway, it's the same house and other living, neobux told me that i couldn't access not because of the timing but because i already accessed with the same ip

No, it's not true. The IP is based on the connection with your ISP, and is he who assigns it to you, your browser has nothing to do with it. If you has a fixed IP, your ISP tells that number and will last until you take the service down. If you has dynamic IP, your IP is assigned each time your modem connects, usually when you reset it. Using a different browser may change something because each stores a different set of cookies for each site, but anyway the sites will see the same IP you have. Try entering www.myip.net and see your IP with different browsers.

No this not true, An IP adress gives the internet provider and your location not the browser, The site owner can see what browser you used thought, but your browser sends this not your IP.
