Earlier this week MÄK released the latest version of the RTI, 4.1. One of the big features of this release was support for IPv6. For those that don’t know much about IPv6, it is the latest version of the Internet Protocol and replaces IPv4. The primary motivating factor behind the creation of IPv6 was the size of the IP address space in IPv4. IPv4 addresses are only 32 bits long. That’s enough for 4,294,967,296 different addresses, but it’s not enough for the size of the internet today.
