Subject: [users@httpd] What IP address is this log entry coming from? (Is "::" a valid IP address?)

I'm using:
CustomLog "/var/log/apache2/access_log" "%a %l %u %t \"%r\" %>s %b
\"%{Referer}i\""
And I occasionally see this right around the time the CPU starts running at
100%:
:: - - [27/Aug/2010:12:28:01 -0700] "GET /favicon.ico HTTP/1.1" 200 - "-"
%a is supposed to be an IP address, so what IP address is "::"? I'm only
somewhat familiar with IPv6 but I've never seen "::" before.
I'm attempting to try to figure out why, on random occasions, the server CPU
suddenly spikes to 100%. I'm not sure where the problem lies. Could be Apache,
MySQL, PHP, or something else (e.g. the OS). This problem has been ongoing for
months now and the only "fix" is to reboot the box, which is a rather
frustrating "solution". The "::" issue is the first possible clue I've gotten.
It seems to crop up only around the times the server is at 100% in the logs.
