The driver supports Internet Protocol (IP) addresses in IPv4 and IPv6 formats.
The server name specified in a connection URL, or data source, can resolve to an IPv4 or IPv6 address. In the following example, the server name MyServer can resolve to either type of address:
Alternately, you can specify addresses using IPv4 or IPv6 format in the server portion of the connection URL. For example, the following connection URL specifies the server using an IPv4 address:
You also can specify addresses in either format using the ServerName data source property. The following example shows a data source definition that specifies the server name using an IPv6 address:
SQLServerDataSource mds = new SQLServerDataSource();
mds.setDescription("My SQLServer DataSource");
mds.setServerName("2001:DB8:0:0:8:800:200C:417A");
...
Note: When specifying IPv6 addresses in a connection URL or data source property, the address must be enclosed by brackets.
In addition to the normal IPv6 format, the drivers support IPv6 alternative formats for compressed and IPv4/IPv6 combination addresses. For example, the following connection URL specifies the server using IPv6 format, but uses the compressed syntax for strings of zero bits:
