IPv6 infrastructure

Dual Stack infrastructure implements both IPv4 and IPv6. This is the recommended infrastructure implementation for using Adaptive Server Enterprise as an IPv6-aware server.

Sybase applications are IPv6-aware. All code to turn Sybase™ Adaptive Server and the Open Client/Server components IPv6-aware was done using the IETF designed primitives, see “Creating or converting for IPv6-aware applications.” The following matrix lists the platform run-time requirements and the specific product and its release version:

Many Sybase products that are Open Client/Server based like XP Server, Backup Server, Replication Server and Open Switch became automatically IPv6-aware due to the layered Open Client Transport Control Layer (CTlib->NETlib) which is IPv6-aware for network-socket operations. An important note is that any DBlib based Open Client product is not IPv6-aware.

For Adaptive Server Enterprise being IPv6-aware is a complex issue because some components within the ASE are 3rd party components and are not yet IPv6-aware. To understand how this impacts Adaptive Server Enterprise the following list shows all functional mechanisms of Adaptive Server Enterprise that are IPv6-aware with respect to the platform / release matrix above:

The following functional mechanisms in Adaptive Server Enterprise do not support IPv6. These mechanisms in Adaptive Server Enterprise are IPv6-unaware. They will gradually (over time) be become IPv6-aware in follow-on releases:
