Browsers use IP addresses to connect, so blocking an IP would also block access to all associated hostnames. Hostnames are used to determine the IP address. Littlesnitch help has a good writeup on the subject Network Basics.
IP addresses shouldn't normally be shown, though. From Littlesnitch release notes http://www.obdev.at/products/littlesnit ... otes3.html
Apparently it hasn't been completely fixed, as yours is the second recent question about it.

Fixed an issue causing Little Snitch to display IP addresses instead of the actual hostnames.
