There are some sites we need to block and it is more efficient to block the entire IP range that belongs to a DNS domain than to try to find each individual web server. One example is myspace.com. Their web sites are spread over several class C ranges.
I know there was a way to find the ranges used by specific domains because I used it before. Since my laptop died I haven't been able to remember where to go to find an IP range that corresponds to a domain.
I would appreciate it if someone pointed me to the link.
