The driver supports Internet Protocol (IP) addresses in IPv4 and IPv6 format.
The server name specified in the connection URL, or data source, can resolve to an IPv4 or IPv6 address. For example, the following URL 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 IPv6 format:
CassandraDataSource mds = new CassandraDataSource();
mds.setDescription("My CassandraDataSource");
mds.setServerName("[ABCD:EF01:2345:6789:ABCD:EF01:2345:6789]");
...
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:
