pay.gov and IPv6

[Matthew Kaufman <matthew () matthew at>]

Random IPv6 complaint of the day: redirects from FCC.gov to pay.gov fail 
when clients have IPv6 enabled. Work fine if IPv6 is off. One more set 
of client computers that should be dual-stacked are now relegated to 
IPv4-only until someone remembers to turn it back on for each of them... 
sigh.
