How can I make my IP address appear to be from another country?

"Adding a proxy will definitely slow down the browsing, especially if the proxy you use is used a lot.

TOR is an option, but there are many others.

Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis"

"This depends why you want to hide you IP address (as this will measure how untraceable you are wanting to be).

If you rent a virtual machine from one of the man VPS providers that are out there and run a web (HTTP/HTTPS) proxy (or any other sort of proxy fot that matter) any connections made through that proxy will appear to come from the VM (and therefore from the country it is hosted in). But you will not be completely untraceable as the sites you are looking at will see the IP address of the VM so if you are planning to do something risky (if, for instance, you live under an oppressive regime and are planning a political statement) this may not offer you the protection you require as someone tracking you down can track you as far as the VM and the provider hosting it who will know who+where you are from your payment records.

For proxying all traffic instead of specific protocols like HTTP and HTTPS you'll need to setup some sort of VPN arrangement rather than just a protocol proxy. In both cases (protocol proxy and VPN) you might find services out there that will mitigate the need to set one up yourself, but you would need to ensure that you trusted the service provider as they will be able to monitor your traffic.

If you are looking to be more untraceable then you will need to use an anonamising network like Tor - but these will never be ""fast"" because of their nature so will fail that stipulation in your question.

If you can be more specific about what you want to proxy (web traffic to/from some sites?, all web traffic?, all internet traffic?, ...), where you are and where you want to appear from we might be able to give you more specific recommendations or pointers to tutorials. Also, knowing why would be helpful. If you are looking to circumvent local restrictions of some kind then that may complicate things."

You might need to get a proxy in US for you.

"This also depends on the method the service defines the IP to location mapping.

Some services will use a strict IANA definition which is by network number. Others use an geo-locating service, which is a table that is periodically updated."
