As a result, IPv6 currently accounts for only 1 per cent of IP addresses. This will have to change. DNS servers receive billions of simultaneous requests. Millions of domain names and IP addresses are changed every day. DNS handles all of these with ease, yet its importance is more fundamental than that.
