Obtaining my IP, strange results

[T <mlist4suntong@yahoo.com>]

Hi, 

I know that whatismyip.org is supposed to return my IP address. But this
is what I got:

$ lynx -dump http://whatismyip.org/
127.0.0.1

This is strange enough but my question is even more strange than this:

I can get my correct IP via checkip.dyndns.org, but after I visit the
whatismyip.org, the return from checkip.dyndns.org will be incorrect:

$ lynx -dump http://checkip.dyndns.org;date
   Current IP Address: 69.158.xxx.xxx
Fri May 12 21:40:22 EDT 2006

$ lynx -dump http://whatismyip.org/
127.0.0.1

$ lynx -dump http://checkip.dyndns.org;date
   Current IP Address: 127.0.0.1
Fri May 12 21:40:36 EDT 2006

This has been duplicated several times. I'm wondering what is the reason
behind that. and how can I solve the problem, since there is no
reliable way to get my IP now. 

Please help

thanks a lot
