none of that info is visible to the public, when you send a transaction all that is visible on the blockchain is the address you sent coins to, the addresses of the output of the coins sent, and the amount sent. no personal information is ever required to transact coins.
I'm confused. When people talk about the "address", is that the random identifier like
1415RPuMbBkagyAnC9mv3v3aZiHpTiFHar (random address I just picked from live public transactions)
Or is it the IP address? If its the IP, where is that information available? I cannot see it in a transactions page:
