13.8.2 IPv6

Internet Protocol Version 6 (IPv6) is now supported in the socket stream interface.

A new type comm:ipv6-address represents IPv6 addresses which can now be returned by comm:get-host-entry .

Functions already accepting an IPv4 address argument, such as comm:open-tcp-stream , comm:start-up-server , comm:ip-address-string and so on have been extended to accept a comm:ipv6-address instead.

The scope ID is supported and a new function comm:parse-ipv6-address converts a string to a comm:ipv6-address .
