覺得會變內網，好似宜家大陸咁。又或者ipv4免費內網，ipv6 有真IP。要公網ipv4加錢。

你以為轉ipv6好過癮？
好多Router的hardware nat只適用於ipv4, 在ipv6下會廢除武功

    Do you know that one of the purposes of launching IPv6 is to eliminate NAT?
Hardware NAT chips are developed to compensate for throughput penalty under NATted environment. There's no NAT in IPv6 so this layer of resource consumption is gone and hardware NAT will become obsolete.

據講話發達地區ipv4一早已經攞咗好多address,未有咁快玩完,但發展中國家就冇喇,所以被迫要用ipv6,的確好多舊野(尤其商業用)都唔support ipv6

其實好多用家唔會理ipv幾,只要返屋企上倒網用倒就得

Ipv6多數isp內部使用 外部用ipv4 好少見v6
加上好多舊有equipment 用v4
用v6對普通user有乜好處

1. Eliminating throughput penalty brought by NAT
2. Allowing networked devices to communicate directly with other devices from internet (but please have your firewall setup properly)
3. Our internet will migrate to IPv6 eventually and if nobody take the initiative for such change then we are stuck.

其實 知唔知nat既作用係咩?
就係轉換 packet內既ip 然後再傳送出去
令 private ip既 device可以同 public ip device 互相傳送數據

而ipv6 冇需要 private ip
唔計 firewall, 所有 device都可以直接聯絡
ipv6 係唔需要nat
ipv6 Router既角色 要著重係 firewall

佢主要想講既係家用設備如ipcam,nas想放出街用既時候，好多都仲用緊ipv4,如果依家全部用哂ipv6，咁呢堆設備點放出街?
