Re: [教學] 升級IPv6：準備篇 （Tomato）
※ 引述《Esh ()》之銘言：
: 對我而言，最實際的問題還是「看YouTube可以比較快」。
: 沒有深入知道理由，只知道這是IP封包規格的改變造成。
: 目前一些網站也有提供IPv6的版本，反正我就來試試看。
這個跟IPv6沒有什麼直接關係, 連其他vpn也可以有同樣效果
本來你連 youtube 是 PC -v4- ISP TP -v4- youtube
像是惡名昭彰的 Hinet TP 就爛到有剩.
你撥上了 HE, 接下來往 youtube 的連線改走 ipv6,
路由變成 PC -6in4- HE -v6- youtube
跳過了有問題的 TP 當然就快了
實測 hinet dualstack ipv6 連 google 還是很慢的
