The drivers support Internet Protocol (IP) addresses in IPv4 and IPv6 format as shown in the following tables.

Table 1. IP Address Formats Supported by 32- and 64-bit DataDirect Connect for ODBC Drivers
Driver IPv4 IPv6
Progress OpenEdge Wire Protocol All supported versions All supported versions
Sybase Wire Protocol All supported versions Sybase 12.5.2 and higher
Table 2. IP Address Formats Supported by 32- and 64-bit DataDirect Connect XE for ODBC Drivers
Driver IPv4 IPv6
Greenplum Wire Protocol All supported versions All supported versions
Impala Wire Protocol All supported versions Not supported

If your network supports named servers, the server name specified in the data source can resolve to an IPv4 or IPv6 address.

In the following connection string example, the IP address for the Progress OpenEdge server is specified in IPv4 format:
DRIVER=DataDirect 7.1 Progress OpenEdge Wire Protocol;
HOST=123.456.78.90;PORT=2055;
DB=OEACCT;UID=JOHN;PWD=XYZZYYou

In the following connection string example, the IP address for the Progress OpenEdge server is specified in IPv6 format:

DRIVER=DataDirect 7.1 Progress OpenEdge Wire Protocol;
HOST=2001:DB8:0000:0000:8:800:200C:417A;PORT=2055;
DB=OEACCT;UID=JOHN;PWD=XYZZYYou

In addition to the normal IPv6 format, the drivers in the preceding tables support IPv6 alternative formats for compressed addresses. For example, the following connection string specifies the server using IPv6 format, but uses the compressed syntax for strings of zero bits:

DRIVER=DataDirect 7.1 Progress OpenEdge Wire Protocol;
HOST=2001:DB8:0:0:8:800:200C:417A;PORT=2055;
DB=OEACCT;UID=JOHN;PWD=XYZZYYou
