Ingres supports Internet Protocol version 6 (IPv6) networks. IPv6 provides more addresses for networked devices and more efficient processing than does IPv4.

Use of IPv6 by Ingres is transparent. Ingres immediately begins using IPv6, wherever possible, as the network is migrated to IPv6.

Ingres 9.1 supports both IPv6 and IPv4 addresses. IPv4 must be used to access versions of Ingres prior to Ingres 9.1.
