IPv6 Support
Jim Tcl has had ipv6 support ever since the WorkWare fork was merged back into mainline.
You can read more about it in the documentation at: socket
Basically it is a matter of specifying -ipv6 when creating the
socket and giving an IPv6 address. For example:
set s [socket -ipv6 stream.server {[::]:2000}]
Note that IPv6 addresses are enclosed in square brackets. This is the same notation used for IPv6 URLs and makes it easy to keep the address:port syntax.
The address returned by recvfrom will be formatted appropriately, so it can be used directly by sendto.
Some simple IPv6 examples are included in the repository. For example: udp6.server
Note that on all hosts I have tried, listening on an IPv6 socket will also listen on the corresponding IPv4 socket. You can try this by running udp6.server and connecting with both udp6.client and udp.client
