Why IPv6 Exists
• Address space
• Address space
• Address space
• Improvements over IPv4
– Security (authentication, encryption)
– Autoconfiguration
– Etc.
• Anticipated problems with the extra
devices to connect to the Internet
– Routing table size
– NAT induced restrictions
– Router overhead growing
– Etc.
IPv6 Today
• Good support in most operating
systems
• Some commercial networks offer IPv6
• Lots of trial networks
• Some IPv6 exchange points
• Academic backbone networks
Where is IPv6 Going
Why lots of addresses ? – why not NAT ?
• Every device to get a routable address
– Peer-to-peer applications
– Gaming and entertainment
– Home “servers”
• LG Internet Fridge
• air-conditioner
• Playstation 2
• Encryption and Authentication
– IPSEC built into headers of IPv6
– Authentication as well
– Flexible to handle other crypto schemes
Mobile IPv6
• PDAs
• Mobile phones
• Wearable devices
Migration tools
• Dual stack
• Tunnelling
– 6over4 tunnels
– Tunnel brokers
– 6to4 tunnels and 6to4 relay routers
Summary
• Manufacturers are ramping up for more
IP connected devices
• Consumer expectations set for peer-topeer connections
• Asia setting deadlines for IPv6 rollout
