While migration to the IPv6 networking standard is not going to have an immediate impact, IPv4 addresses will run out. "It is not something businesses need to worry about now. But 10 years down the line, we will be living in an IPv6 world, to support the internet of things," says Bob Tarzey, analyst and director at Quocirca. From June 6, ISPs will offer IPv6 web content by default. But how should businesses prepare? He says, "Small businesses need to consider how well their networking equipment supports IPv6." he urges businesses to ask their ISP if they are supporting IPv6 now. If they are not, Tarzey recommends businesses look for another service provider that does offer IPv6.
