Just trying to configure cross-cluster query & need to use IPv6 addresses for seeds.

( ES version: 6.3.2 }

Works fine with IPv4 as follows  
put \_cluster/settings  
{  
"persistent": {  
"search": {  
"remote": {  
"ci": {  
"seeds": [  
"10.0.0.51:9300"  
]  
}  
}  
},  
"search.remote.ci.skip\_unavailable": true  
}  
}

How can I specify ipv6 address?  
(I have also tried using dns/hostname but that does seem to work either
