.. warning::
|
|
|
|
The IPv4 address resides in a private IP address range (RFC1918). Thus,
|
|
the Networking service performs source network address translation (SNAT)
|
|
for the instance to access external networks such as the Internet. Access
|
|
from external networks such as the Internet to the instance requires a
|
|
floating IPv4 address. The Networking service performs destination
|
|
network address translation (DNAT) from the floating IPv4 address to the
|
|
instance IPv4 address on the self-service network. On the other hand,
|
|
the Networking service architecture for IPv6 lacks support for NAT due
|
|
to the significantly larger address space and complexity of NAT. Thus,
|
|
floating IP addresses do not exist for IPv6 and the Networking service
|
|
only performs routing for IPv6 subnets on self-service networks. In
|
|
other words, you cannot rely on NAT to "hide" instances with IPv4 and
|
|
IPv6 addresses or only IPv6 addresses and must properly implement
|
|
security groups to restrict access.
|
|
|
|
#. On the controller node or any host with access to the provider network,
|
|
``ping`` the IPv6 address of the instance.
