til / use the ip address instead of localhost

When using localhost, the computer looks up an IPv4 address (typically 127.0.0.1) or an IPv6 address (typically ::1). The application may try one address first, fail, and then try the other. However, in certain cases¹, this approach may not work properly, causing the computer to only attempt one address.

To avoid wasting time on repeated searches and determining the meaning of localhost from /etc/hosts, we can directly use the IPv4 address 127.0.0.1. Although the speed improvements may be small¹, they can add up to a significant amount of time for a large organization.
