## Description

GitHub520 is a DNS resolution accelerator and hosts file optimizer that provides curated sets of IP addresses to bypass slow or broken DNS lookups. It specifically functions as a GitHub hosts resolver, providing optimized mappings to resolve connectivity issues and improve loading speeds for GitHub services.

The project automates the process of improving network performance by fetching current IP address mappings from remote text or JSON endpoints. It modifies the local operating system hosts file to override default DNS resolution, which helps resolve slow connection speeds and image loading failures.

The system includes capabilities for scheduled execution to keep network configurations synchronized. This involves automating hosts file updates through system scripts to ensure that service IP addresses remain current and stable.
