No. The host command will tell you what the reverse name of an IP
address is:
$ host www.rudedog.org
www.rudedog.org CNAME gw.rudedog.org
gw.rudedog.org A 206.124.142.242
$ host 206.124.142.242
Name: dsl-142-242.sea.blarg.net
Address: 206.124.142.242
However, there is no way to figure out that 206.124.142.242 is
www.rudedog.org, www.chezcarrigan.com, gallery.chezcarrigan.com, etc.
The only feasible way to do that would be to transfer every single DNS
zone on the known internet(*) and find the A records that pointed to
206.124.142.242, and even then, that wouldn't tell you exactly what you
want to know.
Note that Apache's mod_info can tell you all of the virtual hosts on a
single IP, but the Apache admin would first have to enable it and second
would have to be stupid (or brave) enough to allow access to it on the
public internet.
(*) This is an exercise left for the reader.
