[squid-users] External IP in access.log

Hello, I have been asked what are external ip address in the sarg reports.

so I had done a search in access.logs and I found follow access among others.

795035 112.215.36.175 TCP_MISS/200 96944 GET

DIRECT/74.204.173.205 image/jpeg

please, released there are two external ip address at the initial
112.215.36.175 and at the end 74.204.173.205.

when I run a sarg report that access it appear like the most used! it
is very strange why it doesn't show a internal ip address instead ?

what is this external access ?

any tip is welcome.

thanks
