Redis clarification of node address and port in cluster mode

hi,

we are testing redis cluster in an ipv6 only setup. The cluster it selfs seems to run fine. But nearly all clients we tried can't work with moved.

The documentation said:

GET x -MOVED 3999 127.0.0.1:6381 Most clients now split "127.0.0.1:6381" with : as delimiter between IP and Port. Or like the stackexchange dotnet client which use the string "127.0.0.1:6381" to connect to. This works well in an ipv4 only environment. But on IPv6 this will fail.

In the moment redis return:

GET x -MOVED 4844 XXX:XXXX:X:X::1:4:6379

This makes it very hard for the clients to parse it. From my point of view "[XXX:XXXX:X:X::1:4]:6379" would be the better way for IPv6.

What is the status of this issue?

We are having similar issues, although with the CLUSTER NODES command returning IPv6 as XXX:XXX:XXX::10:1:6379@26379, which are then parsed incorrectly as IP : XXX:XXX:XXX::10:1:6379, Port: 0, CPort: 26379.

According to RFC 3986, the IPv6 should be represented as [XXX:XXX:XXX::10:1]:6379. This will allow that all clients can correctly interpret the IPv6 returned, regardless of the command used.
