![]() ![]() The Wikipedia Page has good information on it. I don't know if I explained it very well, but it was the best I could do. (Though, for example, larger Cisco switches will use 127.0.0.xx IPs to listen for attached cards and modules, so at least some of other addresses are in use. This would provide the information to local applications, while disabling the ability for somebody else on a LAN to access whatever server software you set up as local. In practice, 127.0.0.1 is usually used as 'the' loopback address, but the rest of the block should loopback as well, meaning it's just generally not used for anything. You can specify the server software to transfer information via the loopback address and your client software could listen in on the loop back address. This can be seen when you have a server-client model application installed on the local computer, but you do not want that information to be accessible remotely. It can also be used to specify to your applications that you do not want your information to leave the host computer. Essentially the ip address 127.0.0.1 points back to localhost or self. The same convention is defined for computer’s that support IPv6 addressing using the connotation of ::1. The address is used to establish an IP connection to the same machine or computer being used by the end-user. For example, if you set up a server on Computer A, you can connect to it by visiting 127.0.0.1 on Computer A. I by no means am an expert and I could be wrong, but 127.0.0.1 is the loop back address, meaning any data directed to that IP will get automatically routed back into your machine. 127.0.0.1 is the loopback Internet protocol (IP) address also referred to as the localhost. 127.0.0.1, however, always points to the computer you're currently using no matter what. Hence, the end user cannot search for computer security help while dealing with malware. It also sees its use in malware approaches to block access to legitimate websites. Playing around with this, Ive noticed that there seems to be some kind of translation happening. IP address 127.0.0.1 is usually found in the Hosts file on computers that are assigned a plain English localhost address. If you suspect that your NIC is not working on a physical level, this makes a very good test. Typically, an IP address is unique to every computer on both your local network and the internet. Through an accidental typo Ive realized that when you try to reach the ip address 127.0.01 it will successfully route to 127.0.0.1. While we all know and love 127.0.0.1 as the localhost, its worth noting that it wont be the localhost forever. ![]() When you do this you are testing to make sure that your information can go down to layer 1 and back up. When you test your NIC, this can be done via "ping 127.0.0.1".
