Support IPv6 and IPv4 dual-stack network listening

Read me

Read this first before creating an issue:

Describe the feature

The TCPServerBase.class only support listen one SocketAddress. The service cannot support both IPv4 and IPv6 dual-stack networks.

Use cases

This will help promote the development of ipv6.

it is not cleat what you mean, a server can only indeed bind on a single local address interface, but it can be IPV4 or IPV6 depending on the configuration of the JVM, can you elaborate ?

I want to bind both ipv4 and ipv6 ip addresses to a port. like this

String[] hosts = host.split(","); List<ChannelFuture> futures = new ArrayList<>(); for (String h : hosts) { ChannelFuture f = bootstrap.bind(h, port); futures.add(f); } for (ChannelFuture f : futures) { f.sync(); }

ok that does not seem specific to IPV4/IPV6 though ?
