Sangeetha Hariharan commented on CLOUDSTACK-1481: ------------------------------------------------- In this case , Vm is part of 1 ipv6 network and 1 ipv4 network. create a dual stack network N1 -domain name- hello1383 create a ipv6 network N2 -domain name- yoyo1372 Deploy a 2 Vms in N1 and N2. >From 1 VM, try to access other VM using its fully qualified domain name. Accessing using N1's domain name succeeds. But access using N2's domain name fails. sangeetha@ubuntu-123:~$ cat /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver fc00:3:1383::e34b:647c:e5bb:63c2 nameserver 10.223.137.181 nameserver 72.52.126.11 search yoyo1372 sangeetha@ubuntu-123:~$ ssh yam-ipv6-ipv4-1.hello1383 The authenticity of host 'yam-ipv6-ipv4-1.hello1383 (fc00:3:1383:0:e5d9:2cdb:a372:88e4)' can't be established.
