LoadRunner enables you to test IPv6 based applications in addition to IPv4 based ones. Script recording supports recording for both IPv4 and IPv6 simultaneously. The code that is generated is non-IP specific. With the exception of Web HTTP/HTML protocols, users are unaware which IP version is being used when replaying the script in a load test. Web HTTP protocols have a Runtime setting that allows you to choose between IPv4 and IPv6 for the replay.
The internal LoadRunner communication between the Controller and Load Generators uses IPv4 communication. To record and replay in both IPv4 and IPv6, install both VuGen and Load Generator on IPv6-enabled computers, as shown in the diagram below.
For more details about IPv6 related changes, see the Preferences View - Internet Protocol.
For a list of the supported protocols, see the Product Availability Matrix, available from the Software Support site. You can also find information here: Protocol Support for Async, IPv6, and 64-bit Recording
