说明
netselect determines the fastest network servers from a list of hosts by measuring packet round-trip time and routing hops. It sends probe packets and ranks hosts based on a combined score of latency and hop count. The output score is calculated as latency multiplied by (number of hops)^3, favoring nearby servers with low latency. Lower scores indicate better servers. Commonly used to select the fastest Debian mirror or DNS server. The companion tool netselect-apt automates mirror selection for Debian systems.
