ANSP is 100% IPv6 NETWORK
From 6 November, 2014, all of ANSP services now operating in IPv6.
The ANSP network has been using IPv6 (Internet Protocol, version 6) since 2004. It has been using IPv6 to exchange traffic with RNP (National Research and Education Network) and private institutions such as Terremark, since 2006, and with the American academic networks, since 2009. However, ANSP’s services continued to operate with IPv4 until last week.
Now the USP Cloud, where ANSP’s servers are hosted or replicated, have also switched to operating with IPv6, enabling all ANSP servers to begin working with that protocol. Since 6 November, 2014, the ANSP network has become fully IPv6.
Implementing IPv6 increases the address space for data packets from 4 to 16 octets, increasing the number of possible addresses from 232 (4 billion) to 2128 (510 trillion trillion trillion), which allows the Internet to continue to grow and develop as it has done until now.
With the increased number of addresses it is not necessary to use the Network Address Translation (NAT) technique, used universally nowadays to generate more IP addresses. Besides having to implement an additional protocol on top of another, some services do not work well with NAT.
The increased address space and the rendering of NAT unnecessary are not the only advantages of IPv6. The more regular and hierarchical header enables the processing of packets by network devices to be more easily implemented on the hardware making them more efficient.
This transition is another remarkable fact in the history of ANSP’s innovative actions, underlining its permanent commitment to delivering a state of the art network to its users.
