hey, I was wondering whether it is possible to create blogs on different IPs? I want to create a network of blogs. So I was wondering is that is possible.
Sure you can. If you have multiple IPs on the server, you can bind apache to all of them so it won't matter which IP is used to get there, all that matters is the name of the host. I've used wordpress mu for some projects but I'm using lifetype for my latest project. You can check it out from the link in my sig. It's only running on 1 IP for now but I can easily add as many as I want. I also give users the option of using one of my domains and a subdomain or using their own domain. I think you can do the same sort of thing with wpmu but with lifetype it is easier to accomplish. Best of luck to you.
