About IPv6 Address Formats

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.
