The difference between localhost and 127.0.0.1

localhost means the local server, and 127.0.0.1 is the native address, their relationship is through the hosts file in the operating system, the localhost resolves to 127.0.0.1. While the actual work, localhost is not through the network card transmission, so, it is not affected by Internet firewalls and the restrictions associated with the NIC, while the 127.0.0.1 to transmit data through the network card, it is necessary to rely on the network card.      This is their biggest difference. The general Setup program, Local service with localhost is the best, localhost will not be resolved to IP, and will not occupy network cards, networking resources. Sometimes it can be used with localhost, but it is in this case that it is not possible to use 127.0.0.1.
