What Is The Problem and Why?
Without enough IP Leases and the Data Tsunami
• It Affects Subscribers Acquisition
• It Affects Connection Hungry VAS Applications
• It Affect Carrier/Service Providers Revenue growth
IANA - Internet Assigned Numbers Authority
RIR - Regional Internet registry
* There is a very good chance it will run out this year

Facing IPv6 implementation
• In the progress migrating from IPv4 to IPv6
• Initial status
• Everything is IPv4
• Transition
• mix of IPv4-only
• IPv4-IPv6 dual stack
• IPv6-only terminals
• End status:
• Everything is IPv6

DNS to the rescue …
• Users don’t remember IPs – they remember names
• A record: www.google.com -> 74.125.155.104
• AAAA record: www.google.com -> 2a00:1450:4008:c00::69
• But only if request is coming from IPv6…

Data Center services - F5 value proposition
• Dual stack technology
• Application proxy “service aware”
• Additional services
• Application security
• Traffic optimization
• Server offload
• WAN optimization
• User access control
• Logging
14
ALG – Application Layer Gateway
• BigIP take decisions on L7 traffic for the following applications:
• SIP
• RTP/RTCP/RTSP
• HTTP, HTTPS
• FTP
• Diameter
• RADIUS
• XML
• DNS
15
IPv6 and IPv4 interoperability
• BIG-IP NATs, SNATs, and Virtual
Servers can automatically serve as
gateways between IPv6 and IPv4
networks.
• NATs, SNATs, and Virtual Servers can
also run in autonomous IPv4 and
IPv6:
• IPv6 client to IPv4 node/pool member
• IPv4 client to IPv6 node/pool member
• IPv4 client to IPv4 node/pool member
• IPv6 client to IPv6 node/pool member

F5 Application Delivery Controller
• Gateway between
IPv4 and IPv6
• Interacts with DNS
• Provides DNS
• Scales to the millions
• IP
• Connections
