You need to be a Dark Sider admin type to see IP addresses and or be gifted special powers to oppress the masses
However, somewherez in the administrative section there will also be an area to identify bots and assign names

It's how you can see Google and Bing are visiting without them actually being members. The thang to remember is that bots are very very fast and can come in swarms like 10 googlebots at once each reading 10 pages, then depending on how a system defines a guest reading {
like number of pages requested} there can appear to be many more visitors than they actually are.
On the plus side it makes it look like a forum is very popular especially if you change it to visitors per day instead of 30 minutes

The downside is a lot of bots are email harvesters, spam/hack bots or just poorly constructed user agents AND they can eat up a lot of bandwidth and burn up CPU time.
Using a lot of bandwidth and CPU, especially on a shared system, slows everything down and acts like a DoS attack. Plus it can stress out your MySQL database and it really sucks having to rebuild a MySQL database when it borks on account of some dubious bot wasn't playing nice
Anywho don't worry ... the point I'm trying to make is the guest number isn't right

Jim said his google ads paid out about $6 a month, there are a lot of factors BUT that sounds like the 1k to 5k ballpark of unique IP addresses

That's around 100 real peoplez per DAY not 30 minutes

Also that's purty good for a simple forum
