What's the URL/IP for the Google cache?

Is it always 216.239.33.100

[yosmc]

I have disabled hotlinking on my domain, so if other people link directly to images on my site they get an error. However, I would like to allow Google to access the images on my site, e.g. when somebody looks at a cached copy of one of my pages on Google. I've seen that the archive is located at IP 216.239.33.100 - is it always that way, or are there different URLs I need to consider?

Thanks!

yosmc,

I allow 216.239.32.0 - 216.239.63.255 so the Google cache will work, as well as their WAP proxy, and several other services and features. These are all Google addresses; Also, the referrer (if present) will always contain your domain name - based on my observations only.
