  2. On 03 Feb 2011 RIPE NCC (Network Coordination Center) stated that in next period IPv4 address space will be exaustedhttp://www.ripe.net/internet-coordination/ipv4-exhaustionWhat does this mean?When the RIPE NCC starts to allocate from the last /8 of IPv4 address space, an LIR may receive only a /22 (1,024 IPv4 addresses), even if they can justify a larger allocation. No new IPv4 Provider Independent (PI) space will be assigned.

  3. In our company this statement raised an alarm and pushed us to find solutionSOLUTION:- NAT IPv4 implementation- IPv6 deployment

  4. IPV6 development in ONE:2009: Getting aware about new technology2010: First Ipv6 Tunnel using tunnel broker and first published web site2011: IPv6 allocation from RIPE. Native IPv6 peering.Participate in World IPv6 day. 3 star Ripenness2012: Dual Stack enabled enterprises services. Participation in World IPv6 day. 4 star Ripennes

  5. How to get started:- IPv6 Discovery- IPv6 Assestment- IPv6 Planning and Designing * dual stack, hybrid, block model * get your own v6 prefix- IPv6 Implementation- Network optimization

  6. IPv6 prefix assignements:- Service provider (LIR): /32- Large end user, Organization: /48- Small end user: /56- SOHO: /64 or /60Do not count available hosts per subnet…………..It doesn’t have sense!!!!

  7. Planning and Designing your own IPv6 infrastructure:- understanding IPv6 128 bit length format- addresing by location (example:2A01:5B8:FEED:HEX1(location)HEX2(desktop/server/DMZ/infrastructure)HEX3&4(Vlan number)::(host IPv6)/64- addresing by type(example:2A01:5B8:FEED:HEX1&2(desktop/server/DMZ/infrastructure)HEX3&4(location)::(host IPv6)/64

  8. Where to go next:- Test applications- Evaluate impact on existing infrastructure- Endure new purchases are IPv6 compatible (HW/SW)- Train your staff- Start small- enable your website * Dual stack * native IPv6 or NAT-PT (or SLB-PT)- Enable Internal connectivity. Pilot IPv6 in your network- Contact your service provider and investigate possibilities for NAT64/DNS64

  9. IPv6 advantage:- Added adresses- Stateless autoconfiguration- Simplifies routing- fewer header fields- Support IPSec natively- Improved Mobile IP support- QoS support-flow label potential- Native multicast- Includes anycast- Backward compatible- Extensible

  10. IPv6 Transition Techniques- Dual stack- Tunnel/Encapsulation * configured tunnels * automatic tunnels 6 to 4 ISATAP Tunnel Broker with TSP Teredo * NAT64- Application layer gateways * Proxy * Load balancer

  11. Some security consideration- Controlling access v4 and v6- Eliminate undesired traffic- Configure your IPv4 Firewall to drop protocol 41 to prevent internet hosts from using IPv6 over IPv4 tunneled traffic * 6 to 4 (protocol 41), ISATAP (protocol 41) * Terredo (UDP port 3544)- Misconfigured network devices and DNS server- Statefull firewall between private IPv6 hosts and internet

  20. FUTURE PLANS for IPv6 expansion in ONE:- Dual stack deployment in Packet Mobile (GGSN, SGSN) - Dual stack deployment for PPPoEusers (BRASs)- Dual stack deployment on all hosted web portalsFirst commercial request for deployment of IPV6/IPv4 dual stack awareness came from Google for their GGC (Google global cash) nodes deployed in ONE

  21. IPv6 is a must, not an option!!!!Question remains, will we be ready for IPv6, or we will wait to be surprised by IPv6?ACT NOW!!!!!
