There is a class of sites for which all addresses are likely not created 
equal:  those with connectivity to both the commodity Internet and 
high-performance research and education networks.  For these sites, 
DNS-based solutions might not prove adequate because applications or even 
pairs of hosts expect to talk only over the high-performance networks; 
falling back to the commodity network isn't an option; it indicates failure 
of the connection.
