Hosts file changes

After making changes to my hosts file, can I make changes take effect
immediately without a reboot? (XP Pro) If so, how?

Is there any wildcard or other way to specify, for example, all possible
domains on a domain name? ie let's say hosts,,,, etc. I am asking for blocking purposes, not
access purposes - there are sites I want completely blocked from DNS

Thanks in advance.
