On IPv6-enabled computers, the network database server listens by default on all IPv4 and IPv6 addresses. IPv6 is not supported on Windows CE.
Usually no changes are required to the database server start line to use IPv6. In a case where specifying an IP address is required, the database server and the client libraries both accept IPv4 and IPv6 addresses. For example, if a computer has more than one network card enabled, it probably has two IPv4 addresses and two IPv6 addresses. For IPv6 addresses that include a port number, you must enclose the address in either square brackets or parentheses. If you want the database server to listen on only one of the IPv6 addresses, you can specify an address in the following format:
dbsrv12 -x tcpip(MyIP=fd77:55f:5a64:52a:202:5445:5245:444f) ...
Similarly, if a client application needs to specify the IP address of a server, the connection string or ODBC data source can contain the address, in the following format:
Each interface is given an interface identifier, which appears at the end of an IPv6 address. For example, if ipconfig.exe lists the address
fd77:55f:5a64::444f, the interface identifier is 7. When specifying an IPv6 address on a Windows platform, the interface identifier should be
used. On Unix, you can specify either an interface identifier or an interface name (the interface name is the name of the
interface reported by ifconfig). For example, the interface name is eth1 in the following IPv6 address:
fd77:55f:5a64::444f;. An interface identifier is required when specifying IPv6 addresses on Linux (kernel 2.6.13 and later). This requirement
affects values specified by the following:
