I like the third option, a well-known name using DNS.<div><div class="h5"><br>

That's the RHEL support, since cloud-init translates a
ubuntu style networking style the ubuntu/debian style format
should also work.

When we discussed this before on the neutron
channel, I thought it was<br>
because cloud-init doesn't support IPv6. We had
wasted quite a bit of time<br>
talking about adding support to our metadata service
because I was under<br>
the impression that cloud-init already did support
IPv6.<br>
<br>
IIRC, the argument against adding IPv6 support to
cloud-init was that it<br>
might be incompatible with how AWS chooses to
implement IPv6 metadata, so<br>
AWS would require a fork or other incompatible
alternative to cloud-init in<br>
all of their images.<br>
<br>
Is that right?<br>

That's certainly my understanding of the status quo, I
was enquiring primarily to check it was still
accurate.<br>

It's not a case of cloud-init supporting IPv6 -
The Amazon EC2 metadata<br>
API defines transport level details about the API
- and currently only<br>
defines a well known IPv4 link local address to
connect to. No well known<br>
link local IPv6 address has been defined.<br>
<br>
I usually recommend config-drive for IPv6 enabled
clouds due to this.<br>
