IP address of a bitcoin address can't really be traced because it can be generated at will any time.

It is meaningless to trace the IP of bitcoin address or bitcoin transaction.
In fact, you can create as many addresses as you want in an offline environment, and you can broadcast your transactions to the network with Tor.

yea only BC who know what your IP , or other online wallet where you keep your coins

If you use blockchain.info wallet, then the site will know your IP, but you could still be hidden behind a VPN or proxy.

VPN and proxy log can be traced.

True, but it is not a easy task for average Joe.
And for the people really trying to stay hidden, I don't think they will use blockchain.info wallet.

You could simply use the blockchain wallet via tor and hide your IP address even from blockchain.info. The same is true for both software and web wallet services. Regardless for the blockchain.info wallet, all that will show up as the node relaying the transaction when you use the blockchain.info wallet is "blockchain.info"

There is really no "IP address of a bitcoin address".
I can generate as many addresses as I want, without any internet connection.

On the other hand, some people may have the IP address of a bitcoin user.
For example, theymos would know my IP and your IP.

User who want to cash out will need to get online eventually.

yeah, but you cant find out regardless if they start tumbling their coins with a coin mixer.

similar how primedice does their hot wallets.

I've noticed if I have 2 wallets... load one up in bitcoin-qt.. then send BTC to my other wallet... for some reason... alot of the time it comes up with my IP in blockexplorer. I know blockexplorer uses the IP that it hears from, not the IP that originated the TX... but how come no transactions to anyone else comes up with my IP in blockexplorer.. and only transactions to wallets I own.. its not possible for blockexplorer/bitcoin-qt to know the adress I'm sending to is is my other wallet.dat

Huh

I've always wondered, how do you route transactions through Tor? It's been a gnawing question, and I guess I just got around to asking about it.

Today - no for all intensive purposes it is not possible as so many people use programs like multibit, electrum and blockchain.info that make it difficult/impossible to potentially determine where a TX came from.

Maybe 2 years ago - yes, if you were watching the network closely enough and had enough nodes then in theory you could make this determination assuming the address you are looking at sends coins to another address.

No it certainly is not possible.
If you think IP relays have something to do with heir IP you are wrong, that's just the IP used to relay the transaction
Bitcoin was made to decentralise and keep people anonymous, not reveal IP's or else it would be the same as using PayPal

I think if you re-use the same adress the chnaces of somebody being able to work out your IP get greater.

Monero has a ton of bugs and nobody is able to fix them because - guess what - Â Monero developers have no idea what thay are doing. I2P integration into CryptoNote? Who told you that would be a good idea??

Long Â story short, i find Bytecoin more reliable.

You realize that without an IP solution any blockchain anonymity is rendered meaningless right?

So is it possible to find the IP address of any Bitcoin user via their Bitcoin address/transaction?

For example, here is a random address:

http://blockchain.info/address/1PFMGybSCDnoq8bHtzQD2vUfyHohsH8FF5

What would be/have been their IP address?

Not really, a lot of encryption to prevent that

Very interesting knowledge from this topic, so its actually possible to listen to for example Satoshi Nakamoto known addresses and wait from which IP it will be propagated. It would tell nationality of Satoshi.

Not really. Satoshi could push the raw tx directly on https://blockchain.info/pushtx, behind VPN and Tor.

I've always wondered, how do you route transactions through Tor? It's been a gnawing question, and I guess I just got around to asking about it.

But, assuming it works how I think it does, it would be next to impossible for anyone to figure out what nationality Satoshi is if he does route it through Tor or a VPN (Or both).

In relation to the OP's question, and as stated by DannyHamilton, you can take guesses, but it will be decently difficult to get a 100% confirmation on what the IP of the sender is. He described the whole process.
