What's the difference in telling a service to run on localhost:xxxx, 127.0.0.1:xxxx and 0.0.0.0:xxxx? I needed to use 0.0.0.0 to get another host to be able to connect to my service.

There is one valid use for the 0.0.0.0 address though: When listening for connections, it means “listen on all interfaces on this computer”. Some programs may erroneously display 0.0.0.0 where a value is …

Isn't 0.0.0.0 supposed to listen to all interfaces? So basically, how exactly does a 0.0.0.0 binding work from network perspective? how does ping 0.0.0.0 work only for loop-back and not for other interface?

127.0.0.0/8 - This block is assigned for use as the Internet host loopback address. A datagram sent by a higher level protocol to an address anywhere within this block should loop back inside the host.

又邀请我干嘛。无穷不能按照有穷来理解。把0.0.....01视为0没问题，乘以一个有穷数它还是0。0.0..01没法通过有限次加法或乘以有限数得到0.9999...。 尝试把无穷纳入到有穷数的四则运算，是一个不错 …
