First, it is price noting that getting your IP will not determine your pockets tackle. To allow them to’t connect with you after which look you up on the blockchain to see who you’ve got been buying and selling with. Associating an tackle with an individual takes regular investigation, like looking out your pc or associating you/your IP with a put up on the web containing your tackle.
For 1:
Until somebody logging the connections to their bitcoin consumer they usually determine to make it public, there’s no public file of it.
That stated, what most could be nervous about is not that their IP could be publicly printed, however that sure organizations might be able to determine them. A method these organizations might determine you is by working their very own bitcoin consumer and logging their web site visitors (TCP on the port BTC makes use of). This might be very straightforward to do, so whether it is one thing you are involved about, you need to assume it’s being achieved. (If you wish to know the way straightforward, search for wireshark. It may log all site visitors in your native community.)
Assuming somebody is logging IPs on the bitcoin community, the one hope of not being logged is {that a} singe node solely connects (on common) to round 8 friends (however that is configurable). This small quantity means you’ve gotten a considerably small probability of connecting to them.
However, relying on how peer discovery works, it might even be potential to be discovered by the logger asking for friends. That’s, there must be a way of discovering friends within the btc community. This might probably be exploited to determine numerous IPs connecting to the btc community. (To be express, I have never studied the particular means peer discovery works, however from common understanding of programming and networks, it appears very believable.) If this had been the case, then the truth that a node solely connects to about 8 friends is pointless, since you would not want to attach on to the group to get logged; they may discover you by asking others for brand spanking new friends.
For two:
When you ship them to a paper pockets and by no means connect with the btc community by a consumer working in your pc, then no, your IP cannot be found. However, the one option to retrieve them from the paper pockets is to import it into an digital pockets of some variety, which, whenever you join that digital pockets to the community to spend them, will determine you.
