Why DNS can’t block literal IP addresses?

Example: OpenDNS block “kproxy.com” but not its IP Address (192.95.4.125). Why this? Isn’t the same internet site? In this case the option “Block Literal IP addresses” in pcwrt is excellent.

DNS does not block literal IP addresses because DNS server is not consulted when you already have the IP address. I.e., your computer only contacts the DNS server when it needs to get the IP address for a domain name. If the IP address is already known, the computer does not contact the DNS server.
