hello, i need to change my ext. ip, but i am quite inexperienced; not a total noob tho.

so how should i be able to do that? i found few pointers on the web but they were all
explained bit poorly.

oh, and my external ip is dynamic as far as i know.

Your IP is leased to you from your ISP and the length of the lease varies. One ISP I was with leased it for 24hrs, another leased it for use only while my connection existed.

Basically you need to switch off your router/box until the lease runs out, at which time when you reconnect, you will be issued a new one.

As you mention, if it was static you would need to get your ISP to change it.

yea, my lease has 24h longevity too. if ipconfig tells it right.

so basicaly what i gather... router obtains the lease every 24 hours. if i log on onto the computer in that time it will renew the lease and my ip will remain the same.

so should i turn off the router or modem for 24 hours or just a turn them off/on at the time of lease expiration - turn it off before and turn on after?

You need to configure your software to use a proxy. Many programs do not support this; however web browsers like Firefox and IE do, if that is what you need the proxy for. Just find a list of proxies on Google - basically you want a list of IPs and ports. Be sure that your proxy isn't a "transparent proxy", or else your IP won't be masked. Then, in Firefox for example, you would go on the menu to Preferences ->Advanced->Network->Settings, and fill out the IP and port of the proxy accordingly.

Basically a proxy is just a server that stands between your computer and the server you're trying to reach. It receives the information that you send it (requesting a web page, for example), and forwards it to the server. But since *it* is now the one sending the request, not *you*, the remote server sees the IP of the proxy, not your IP.

Also, if you really want to be anonymous, take a look at Tor + the torbutton extension for firefox. Tor is similar to using a proxy except it encrypts your data multiple times. It then sends that data through a web of multiple computers, with each computer decrypting a layer of the data. It would help to take a look at "web proxy" and "onion routing" on wikipedia.

so i've done some research on proxy lists and apparently there's a whole bussines with them out there. quite hard to find something reliable and with a decent latency.

i was looking for anonymous proxies and came across these PlanetLab/CoDeeN servers. most of them have good latency and are anonymous but have rather shady restrictions that seemed to pop-up in 8 cases from 10. something in a vein of: ""You are trying to use a node of the CoDeeN CDN Network. Your IP address is not recognized as a valid PlanetLab address, so your request rate is being limited." seems strange that all those proxy lists seem to crawl with them.

just to verify something out... when i use "distant" proxy, like something overseas, is there a decrease in bandwith? this is a bit confusing as i am from Europe and when i checked the latency info on some proxies, the US ones seemed to have less latency than some EU ones. so i do not know exactly if the latency is measured according to "me" or the site/server thats it displayed on.

Yeah, proxies are great...it's just a matter of finding a good, reliable one. If anyone has any lists that they have run through a checker and want to share... :roll:

Yes the FBI should be able to supply you with a list, as the best ones are owned by them ;) .
