If they're not running Bitcoin, then you won't be able to communicate with them to get the public key to send to. The transfer will fail.
There is no encryption. You can't encrypt with ECDSA keys. Satoshi planned a system where a "Bitcoin signing address" could be listed with an IP address so man-in-the-middle attacks wouldn't be possible, but this was apparently abandoned along with the rest of the feature.
Topic: Sending bitcoins to an IP address (Read 1659 times)
Bitcoin spam would be so easy to do if I could send a message. I want to try it to give out free coins.
but it would be spam that you get paid for reading it (or ignoring it)
i'm more worried that it could be used to wash coins
anyone with a ipv4 address could run bitcoin client,
wait for a transaction + confirmations and forward
the coins somewhere else, effectively washing them clean
i'm more interested in the chat over bitcoin feature. pitty it will be gone
that means gabbing old sources, "patch" them and summon a bitchat network for testing

Sending by IP address isn't really used anymore, it'll probably be removed in a future release entirely (right now it's off by default). Ignore it.
but it supports attaching a message ...
i wanted to try it and see if the message was encrypted with the same key as the coins
and if it's usefull as a means of chat ...
will it work or will i just burn the bitcoins?
i see you wrote "ïgnore it" but that's not an option

What happens if the IP address is not running the bitcoin software?
