> ########################Run hotrod client with pure IPv6#############################################
> Hotrod client fails when want connect to server, below is exception from pure IPv6 machines it doesn't really undedstand IPv6 address it should connect."Could not connect to server: /0.0.10.60:52" Here should
> be IPv6 address but it looks like some wrong IPv4 address it want to connect to and I use complicated address 2620:52:0:105f:0:0:ffff:32%2:11222 as host variable and it is not specified in /etc/hosts

> Then is the same problem in ConfigurationProperties.java getServerList() method we add address to addresses <<<addresses.add(new InetSocketAddress(host, port));>>>

> {code}
> but we have 2! different inet addresses with the same hostname one is 127.0.0.1 and other ::1 and if i run it on IPv6 there should be ::1 and not 127.0.0.1!

> org.infinispan.client.hotrod.configuration.ConfigurationBuilder has this method

> And what if I put in <servers> argument something like addServers("[fe80::3e97:eff:fe19:3045]:11222;[fe80::3e97:eff:fe19:3046]:11322")? I think that It is not parsing correctly and we can use
> <servers> argument something like addServers("localhost6:11222; localhost6.localdomain6:11322") or other ipv6 hostnames.
> Because I want to use ip addresses and not hostnames and not to change /etc/hosts file only for mapping ipv6 address to some dummy hostname
