The Ping of Vista informs the local address of IPv6 format

Vista's new TCP/IP network protocol stack fully supports the IPv6 format. Do you want to know the IPv6 format of the local address 127.0.0.1? Ping from Windows Vista tells you that many users may feel that the network speed of Windows Vista is not as high as that of Windows XP. In fact, this is because of the number of TCP/IP connections, microsoft may limit the number of connections in future patches, because Windows Server 2008 is 44 times faster than Windows Server 2003. So we need to trust future Vista. The Vista zone shows you the following:

The implementation method is very simple. Enter cmd in the Start Menu of Vista and press enter to open the command prompt. If you enter ping localhost, the returned data packet is not 127.0.0.1 but: 1. This is the local address in Ipv6 format, as shown in 1:

Figure 1

Why? This is defined by the hosts file of Windows Vista. We open the hosts file in notepad in the C: WindowsSystem32driversetc folder and we will see the following ing relationship, as shown in Figure 2:
