Keep IPv6 in mind when developing smart grid architectures

It is also important to remember that, moving forward, IPv6 will likely be a prominent network protocol as more countries run out of available IPv4 addresses.

Overcoming IPv6 issues
IPv6 is a theoretically-superior network protocol, but it does a few things differently when it comes to packet transmission and verification. As a result, working with IPv6 systems can prove risky because some security threats emerge while organizations develop methods to address IPv6-specific issues. The technological solution still has the potential to be a much more secure option than IPv4, but it may take some time to get there. As a result, utility providers trying to use IPv6 to prepare their network for the future must carefully plan to deal with any security issues that may come from using the protocol.
