IPv6 Support

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.

IPv6 Deployment

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.

Protocols Supported

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

Protocol Support Limitations

Support for IPv6 is available with the following limitations:

  • Web HTTP protocol
    • FTP from Web is not supported
    • Web Breakdown is not supported
    • Kerberos is not supported
    • Spoofing from Web is not supported
    • PAC file is not supported
  • Webtrace

    • IPv6 Webtrace is not supported on 6to4 outgoing network interfaces.

    • IPv6 webtrace does not support RawSocket mode

  • General limitations
    • Replay failures may occur because of a IPv4/IPv6 switch between recording and replaying.
