IPv6, or Internet Protocol version 6, is a next-generation internet protocol that was created to replace the current internet protocol, IP version 4. Its growth has already reached more than 9 million domain names and 23% of all networks, according to the State of IPv6 Deployment 2017 survey , conducted by the Internet Society .
Brazil is among the ten countries with the highest volume of internet traffic using the IPv6 protocol, according to a report by Akamai , which also revealed that the total national canadian ceo email list volume rose from 8% to 13% in 2016, causing Brazil to rise from 13th position to 9th place in the ranking, tying with the United Kingdom. Ahead of Brazil are Belgium (38%), Greece (25%), the United States (22%), Switzerland and Trinidad and Tobago (tied with 21%), Germany (20%), India (17%) and Estonia (16%).
Therefore, it is no secret that IPv6 has been gaining a lot of ground. This protocol allows for a much larger number of combinations compared to the old IPv4 model. These combinations are numbers that identify each machine connected to a network. While IPv4 allows for 4.3 billion addresses, IPv6 allows for 340 trillion trillion trillion addresses.
Brazil's 9th position in the ranking of countries that most use the IPv6 protocol can be attributed to the actions of Anatel, which, since 2015, has been encouraging the adoption of the new protocol: encouraging access operators to provide IPv6 addresses to consumers and obliging manufacturers of connected devices to implement support for IPv6.

Greatest resistance to change is in the business sector
Despite the rapid growth in IPv6 adoption in Brazil, experts point out that the greatest resistance to change comes from the business sector, even considering that the Internet of Things will be an area of widespread adoption of the new protocol. The Internet Society study showed that a major obstacle to the implementation of IPv6 – or any new developments in this area – is the installed base.
The view of most CIOs is that IPv4 has been running in the enterprise for 20 or even 30 years and has worked well. So why implement something new that may not work? That being said, a common consideration among enterprises is that IPv6 does not offer extraordinary benefits over IPv4, which would not justify its replacement.
However, this is an unfounded view, as most companies are unaware of the advantages that IPv6 can bring, especially in terms of network performance. According to the Asia-Pacific Network Information Centre ( APNIC ), IPv6 outperforms IPv4 in many Internet applications. And according to Facebook, IPv6 is also, on average, 15% faster than IPv4 on mobile networks in the United States.
