Now that IPv6 is progressing and being deployed more and more, there is a need for a change to the underlying infrastructure. Most providers today use MPLS as their core technology to support a vast number of services to their customers, including Layer 3 VPNs. Larger enterprise networks have also implemented MPLS within their own core in a private MPLS cloud.
