Videotron Ltd. announced Wednesday that it has begun implementing IPv6 Internet protocol to avoid a dwindling number of IPv4 Internet addresses. Experts say that the number of IPv4 addresses that can be allocated to Internet service providers (ISPs) will run out this year. “The roll-out of the Beta version of IPv6 will give early adopters a chance to get in on the ground floor," Pierre Roy, vice-president of engineering, research and development at Videotron, said in a release. "IPv6 is an important development that will help keep the Internet as open and innovative as the technology permits." IPv6 is superior to IPv4, the first Internet protocol, because it offers a larger address space and provides increased flexibility in allocating addresses and routing traffic. Videotron said IPv6 will eventually become an integral part of Videotron's cable Internet access service and that it is available to residential customers who want it and who have the WiFi router that Videotron has been offering since January. Videotron is a subsidiary of Quebecor Media Inc.
