This field is populated by apr_sockaddr_ip_get() in Apache Runtime  
library. The field
can be populated with either IPv4 or IPv6 addresses. On a Mac, when  
you use the
string "localhost" it is as far as I know actually using an IPv6  
connection to Apache and
"::1" is what the Mac is using to identify that IPv6 client.

What do you want the remote IP address for? Depending on what you  
want to do,
there may be better ways of doing it.
