端口转发是把一个端口转发到一台电脑。它告诉路由器哪台电脑处理连到这个端口的连接。所以收到的是那台电脑。
如果你没设端口转发，入站连接就到不了任何电脑，别人发到这个 IP 会提示连不上接收方，什么都发不出去。通过 IP 发送时，你还是发到一个比特币地址，只不过你的电脑连到那个 IP，从它那里拿到一个新的比特币地址，把交易直接交给对方，并确认已收到、已接受。
应该有人把自己的固定 IP 发出来，让大家试试通过 IP 发送，也顺便给那人送点免费的钱。
比特币地址里有个 32 位校验码，所以你不可能手误输错成一个无效地址。
第 4) 条，如果你发给了一个已经放弃或弄丢 wallet.dat 的接收方，钱就丢了。可以顺带说一句：既然流通中的钱总量少了，大家手里剩下的钱就稍微更值钱一点，也就是"自然通缩"。
英文原文
Port forwarding forwards a port to one computer. It tells the router which computer handles connections to that port. So that's the computer receiving.
If you didn't set up port forwarding, then incoming connections won't go to any computer, and attempts to send to that IP would just say it couldn't connect to the recipient and nothing is sent. When sending by IP, you still send to a bitcoin address, but your computer connects to that IP, gets a new bitcoin address from it, gives the transaction directly to the them and confirms that it was received and accepted.
Someone should post their static IP so people can try out sending by IP and also give that user free money.
There's a 32-bit checksum in bitcoin addresses so you can't accidentally type an invalid address.
If 4) you send to a recipient who has abandoned or lost their wallet.dat, then the money is lost. A subtle point can be made that since there is then less total money in circulation, everyone's remaining money is worth slightly more, aka "natural deflation".
