Distcache is part of the infrastructure of FreeBSD. But it is just a workaround for missing IPv6 support with a different set of problems and requirements. If i don't use the ports-tree, for example because of building development versions i am still hit by this issue. It is also often a time-issue. If there is a port with a security issue i upgrade it immediately. In this case the distfile is normally not in distcache. Yes, we could possibly argue that the impact at the ports-tree is much less, because of the distcache-workaround. But it is a workaround and not intended to fix the IPv6 issues. It is sponsored and there is no guarantee of uptime. This servers can went away anytime. Also it is just a mask for the basic problem. IPv6 exists for 15 years, IPv4 addresses are nearly exhausted and IPv6-only connections increases rapidly, while many services are not reachable via IPv6. Therefore we need more persons to be aware of this problem. Greetings, Torsten
