As more IP applications are developed and information resources increase, networks require additional IP addresses. Due to the increased demand on addresses, the IPv4 address pool is running out and the requirement for larger contiguous blocks of address space will not be available in IPv4. IPv6 can provide for this address demand.
- I believe that IPv6 adoption can also bring immediate benefits in the form of improved network topologies and security. Network end points can be better defined to all other network points through the expansion of address assignments – NAT can go away.
- Making websites and IP services available via IPv6 will depend on network structures and the services themselves. This effort may include updating equipment and software for IPv6 compliancy, requiring support from ISPs for IPv6 in the form of tunneling IPv6 over IPv4 (dual stack), training internal network support staff on IPv6 and working on network renumbering for transitioning to IPv6.
- Based on my own interactions at XO I have found that those involved in the transition to IPv6 will look for the least impactful process of acceptance. Maintaining interfaces with present IPv4 environments brings to the forefront the dual-stack solution. This arrangement requires that all elements of IP connectivity such as the IP network, customer premises routers and switches and IP providers along the way be able to support IPv4 and IPv6. The majority of the Internet is now equipped for dual-stack and most root name servers are IPv6 capable, and Top Level Domains (TLDs) are serviced by dual-stacked domain name servers.
My conclusion regarding IPv6 adoption is that the conversion to IPv6 across the Internet is inevitable. Converting to the full IPv6 environment immediately is not required but accepting the changeover from IPv4 should be high on the list of things to do over 2012 and 2013 to best maintain an effective presence on the Internet.
