Comment(by dd32):

 +1 for including a check in core.. -1 for just having a comment.

 This doesn't only affect load balances, It also affects extracting the
 correct IP when the web browser is behind a proxy.

 Look at what other software which relies on IP addresses a bit more has
 done, for example, docuwiki:
 http://dev.splitbrain.org/reference/dokuwiki/inc/common.php.source.html#l591

 Sure, Its a bit complex for what we need.. but it shows that if IP's are
 to be stored/mentioned (ie. comments), WordPress might as well get it
 right.

 It can even be in a function such as that and only called when needed (ie.
 comment being added) to reduce server overheads, most page loads dont need
 the "real ip"
