What IPv4 and IPv6 to use for your vCDN domain

For IPv4 you should use 88.208.31.2 .

To get IPv6 you should add your domain to vCDN first(via panel or via ticket). After passing few minutes you can check IPv6 for your domain. 

# For Windows, MacOS 
nslookup -query=AAAA vcdn.example.com ns1.ahcdn.com

# For Linux
dig +short vcdn.example.com @ns1.ahcdn.com AAAA
or
