XboxFastZ v1.2.0 — Smart Endpoint Discovery

This release removes XboxFastZ's dependency on the upstream-maintained IP.*.txt files for automatic endpoint selection. XboxFastZ can now independently discover and select suitable endpoints for the user's current network.

Added

  • Added EndpointSelectorService for automatic, low-bandwidth endpoint discovery and selection that does NOT rely on the upstream-maintained IP.*.txt files.
  • Candidates are discovered independently by DNS-resolving the bounded, hardcoded catalog of real Xbox/CDN download domains in DnsMappingGenerator.HostRules (e.g. assets1.xboxlive.com, xvcf1.xboxlive.com, gst.prod.dl.playstation.net, …). Discovered IPs are capped at 60 candidates.
  • Selection uses a cheap-to-expensive funnel: ICMP reachability/latency → small HTTP latency probes (packet-loss estimation) → small 4 MB ranged speed test on the top 5 finalists → rank by measured throughput (latency as tie-breaker) → automatic selection.
  • Wired the DNS-based selector into the existing "Fastest Akamai IP" auto-feature. The legacy IP-file race-based selector is no longer used as the automatic selector.

Performance

  • Cheap connectivity/latency checks run before any speed test; the speed-test stage downloads at most 4 MB per finalist instead of the 30/50 MB used by the Speed Test tab.
  • Concurrent ICMP stage with a hard 3-second cap and early stop, minimizing wasted probing.
  • Bandwidth is bounded (≤ ~20 MB worst case) and cancellation is preserved throughout.

Preserved

  • Existing Speed Test tab workflow and per-IP full speed test are unchanged and still use the IP files.
  • The legacy IP.*.txt files, loaders, and related services are retained for backward compatibility; they are not deleted.
  • On discovery failure the currently working endpoint is preserved and a clear failure result is returned (no silent fallback to IP-file candidates).
  • Network Diagnostics from v1.1.0, XboxFastz branding, and original author attribution/donation information are preserved (USDT TRC20: TT9CzksU5KuXkkYaox2ifvF5tbGaQRmSZw).
