  13. 13. Challenges (My view) ● Mindset ●My IPv4 works fine, I won’t need IPv6 ●Martian Law: Don’t change it unless it is broken ●Wait: Let’s see how others deal with it ●Lack of confidence: If anything goes wrong ● Technical ●Lack of awareness: IPv6 seems too complicated ●Compatibility: Hardware and software not supported ●Upgrade: Involves $$$ ●Organization specific issues bdNOG 5 and ION Bangladesh 2016 awal@bdren.net.bd 13
