Customer complains that they want to do staging hardware device  using ZTP by  IPV6 environment,

when they was trying staging using same IPV6 prefix on wan side they were not able to complete.

Staging script used was as below : Eg :

[admin@versa-flexvnf: scripts] # sudo ./staging.py -w 0 -c 2001:1::1 -s 2001:2::2/64 -g 2001:2::1 -l SDWAN-Branch@org.com -r Controller1-staging@org.com

[sudo] password for admin:

Invalid controller IPv4/FQDN 2001:1::1  <-- Error 

Correct format is as below for IPv6 : Eg :

admin@SDWAN-Branch1:scripts$sudo ./staging.py -w 0 -c6 2001:1::1 -s6 2001:2::2/64 -g6 2001:2::1 -l SDWAN-Branch@org.com -r Controller1-staging@org.com
