On some of my netbsd boxes I've had to add the following to /etc/rc.conf:

# prefer IPv4:
ip6addrctl=YES
ip6addrctl_policy=ipv4_prefer
ip6addrctl_verbose=NO

The problem appears to be that on certain setups netbsd doesn't seem to
promptly discern when IPv6 isn't available and just keeps trying for way
too long before falling back to IPv4.

FWIW, many system tools, ie. pkgin(8), have a '-4' option to force IPv4.
