IP_ADDRESS_VERSION (Parameter)

Parameter: IP_ADDRESS_VERSION

Definition

The version of IP addresses which must be used when host names are resolved

Description

This parameter defines the version of the IP addresses which must be taken into account during host name resolution. This parameter gives the possibility to specify whether SAP CC must work with either IPV4 or IPV6 addresses.

Note

Do not specify IPV4 or IPV6 addresses in the instance map if this parameter is respectively set to "IPV6" or "IPV4". This kind of configuration prevents the system to start.

IPV4 : Host names are resolved as IPV4 addresses. IPV6 addresses are not taken into account.
IPV6 : Host names are resolved as IPV6 addresses. IPV4 addresses are not taken into account.
