Re: v4 side unmodifiable
I don't completely agree. If certain applications decide to use Teredo if
native neither 6to4 is not available, because they prefer IPv6 even if
performance may seem lower, avoiding implementing a NAT traversal, because
it is actually about the same as using Teredo, I don't think is a bad coding
practice. Is it just a developer decision to use or not the default OS
policy table. This is also the reason this table can be modified ! But you
many need to avoid modifying it because that will affect all the
applications.
