IPv6 Enabled Contents
bdNOG 5 and ION Bangladesh 2016 awal@bdren.net.bd
● Total 69 websites are IPv6
enabled including
international websites
● Local contents:
●Out of Alexa’s top 500
websites only 8 local
websites are IPv6 enabled
●Apart from that couple of
more local websites are
reachable via IPv6
●Most of them are resolved
through Cloudflare

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

IPv6 deployment in

IPv6 Address Plan
● First /36 used for backbone infrastructure and critical services.
● Remaining /36s are for customer delegation
● Each customer will get a /48.
● Subnetting BCOP

IPv6 Configuration
● Followed similar steps as IPv4
● Hierarchy:
●Interface Configuration
●IGP (IS-IS)
●iBGP and MP-BGP
●eBGP
●Servers and Services
●Monitoring tools
● Sanity check:
●Similar command syntax as IPv4
●Peering, advertisement and routing table
