Hi guys,

We found when it was changed and the reason why:

https://issues.apache.org/jira/browse/CLOUDSTACK-4811


I already traced the code and we will change the NetUtils class in order to make it compliant
with the RFC 3021

The fix will be on ACS 4.6.0 and back ported to the new release 4.4.4.

Cheers,
Wilder

Exactly!
Left my mail in outbox and missed your reply ;-)

@Sanjeev, since you answered the original mail.. Do you know when/where this check was added?
Or else I’ll search for it. Let’s open an issue and resolve it.

Thanks,
Remi

You can assigned the network address as a valid ip address from a /31, and this is defined
in RFC 3021 (http://www.ietf.org/rfc/rfc3021.txt).

This is widely supported on network gear, and in modern operating systems.

Hi,

This question was answered here as well:
http://markmail.org/message/m7vi342uwm4zr5iv

Support was removed as /31 has no available ip addresses.

Hi Devender,

You have started quite a discussion in our office about using the .0 and putting a host on
the cast address …...

Just as a matter of interest, why do you do this - we are presuming it does actually work
;)

Grts!

Hi Cloudstack Team,


We had no problems building and using /31 networks on 4.2.0, but after our upgrade to 4.4.2
 we are no longer able to add new ones.
We have a lot of them already in place.  As an example I pasted some output from cloudmonkey
on a link that is already established and working.
Does anyone have a workaround, or can point me in the right direction for a patch?
