The number of IP addresses and current routing schemes cannot accommodate next-generation applications in a client-server and peer-to-peer global environment. IPv6, as a 128-bit protocol, is supposed to quadruple the number of available IP addresses-enough so that each individual on the planet could be assigned thousands of addresses. Since companies in the billing space will have to be able to handle the new capabilities and built-in service options introduced by IPv6, changes will need to take place within the software and the database fields that occupy addresses. Currently, IP addresses are defined as four groups of digits separated by dots. With IPv6, there will be a need for five times the number of digits when entering an IP address.
