What is the purpose of the Microsoft Loopback Adapter?

When sending messages to 127.0.0.1 (or the localhost) the internal network driver typically handles this by shortcutting a few steps. If you have a networksniffer/protocol analyzer like wireshark, it can not see these shortcutted packets. By using a loopback adapter, the messages get send much further through the stack, enabling programs like wireshark to capture … Read more

What is IPV6 for localhost and 0.0.0.0?

As we all know that IPv4 address for localhost is 127.0.0.1 (loopback address). Actually, any IPv4 address in 127.0.0.0/8 is a loopback address.
