In my blog post last week, I shared my thoughts on SDN in 2015, after reading Sean Michael Kerner’s article in Enterprise Networking Planet. This post will cover a few of my thoughts on IPv6.
Once the initial scares surrounding IPv4 address exhaustion passed, enterprises have taken a relaxed attitude to deploying IPv6 (if they deploy it at all). Given that there are sufficient IPv4 addresses for enterprises to use internally and well-proven solutions for implementing NAT at the LAN/WAN boundary, there doesn’t appear to be a compelling reason for enterprises to adopt IPv6 internally in 2015. Furthermore, most network architects, operations and support teams are very familiar with designing, supporting and troubleshooting IPv4 networks they are less familiar with performing the same with IPv6 or mixed or tunnelled IPv4/IPv6 networks.
Has your organization adopted IPv6? If not, are you planning to? We’d welcome your thoughts and comments.
