Comment 2 for bug 1663340

In order to support IPv6-only and IPv4/IPv6 dual-stack environments, MAAS now makes use of IPv4-mapped IPv6 addresses for its basic operation. Normally this ensures compatibility with all combinations of address families.

Being that IPv6 has been in development since 1995 and has been in the Linux kernel since 1996, I don't think MAAS should need to assume it doesn't exist.

Can you use some other mechanism to disable IPv6 in your environment, such as disabling the acceptance of IPv6 router advertisements?
