Correct way to connect with IPv6 cluster

[LazyHippogriff]

Given below is the definition of ip_port_separator as given in hircluster.c
#define IP_PORT_SEPARATOR ":"

How should I connect with my cluster which has got only IPv6? IPv6 has already got ':' in the IP address. Should I change the macro?

The separator is searched from the beginning of the address string, and one possibility to handle IPv6 is to search from the end of the address string instead, see commit.
In this fork, we have added IPv6 support. We have also fixed memory leaks, allocation failure handling and added features like TLS support. Feel free to switch to this fork.
