Each node in an Oracle Grid Infrastructure cluster can support both IPv4 and IPv6 addresses on the same network. The preferred IPv6 address format is as follows, where each x represents a hexadecimal character:
xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx
The IPv6 address format is defined by RFC 2460 and Oracle Grid Infrastructure supports IPv6 addresses, as following:
Global and site-local IPv6 addresses as defined by RFC 4193.
Note:
Link-local and site-local IPv6 addresses as defined in RFC 1884 are not supported.
The leading zeros compressed in each field of the IP address.
Empty fields collapsed and represented by a '::' separator. For example, you could write the IPv6 address 2001:0db8:0000:0000:0000:8a2e:0370:7334 as 2001:db8::8a2e:370:7334.
The four lower order fields containing 8-bit pieces (standard IPv4 address format). For example 2001:db8:122:344::192.0.2.33.
