By all accounts, the Internet’s transition to IPv6 has been a slow affair.
In recent years, though, perhaps inspired by the exhaustion of the IPv4
address space, IPv6 usage has been on the
rise. There is a corresponding interest in ensuring that applications
work with both IPv4 and IPv6. But, as a recent discussion on the OpenBSD
mailing list has highlighted, a mechanism designed to ease the transition to an
IPv6 network may also make the net less secure — and Linux distributions
may be configured insecurely by default.
