The client and internal networks must be in the same IP family: IPv4 or IPv6. NSP functions communicate internally and externally using only one protocol version.

Note: Only IPv4 is supported for communication between an NSP deployer host and an NSP cluster.

Concurrent IPv4 and IPv6 NE mediation is supported using separate interfaces, or using one interface that supports both protocols.

The IP version support for integrated components varies, as described below.

NFM-P

The NFM-P fully supports IPv6 for mediation and client communication; integration with an IPv6 NSP system has no special requirements.

WS-NOC

The WS-NOC supports integration with an IPv6 NSP system.
