qanet02nue.qa.suse.de and qanet03nue.qa.suse.de can not be reached over neither IPv4 nor IPv6 

 ## Observation 

 ``` 
 $ ping qanet03nue.qa.suse.de 
 PING qanet03nue.qa.suse.de(2620:113:80c0:80a0:10:162:0:63 (2620:113:80c0:80a0:10:162:0:63)) 56 data bytes

 ssh access works, http not. 

 So two problems: 
 1. IPv6 DNS resolution broken 
 2. web interface not accessible 

 ## Acceptance criteria 
 * **AC1:** Only resolvable DNS entries exist 
 * **AC2:** web interface http://qanet03nue.qa.suse.de and/or https://qanet03nue.qa.suse.de accessible as well as http://qanet02nue.qa.suse.de (either HTTP or HTTPS) 

 ## Suggestions 
 * Check for firmware upgrades for these switches 
 * Optional: Apply the same solution The switch is reachable over ssh, try to other QA switches to prevent further problems there reboot it 
 * Check dhcpv6 setup on qanet to understand which v6 address these switches should have 
 * If IPv6 is not feasible to use at all remove AAAA records 


 ## Workaround 
 If the over SSH if web interface is not available a manual power cycle can help enabled
