Somebody should tell the nytimes.com about this being a bad practice,
many of their images are linked to ip addresses directly and will
certainly fail in the future (this year, mobile) networks that will
use NAT64/DNS64.  I am sure users will find other places to view their
news when nytimes.com fails to work in these ipv6-only networks.

Small summary of the problem of IPv4 literals and how they will break
in certain IPv6 environments that will be deployed this year
