This Subnet Mask is it suppose to be like the above? Or does it need to be like this
212.216.22.67 | 255.255.0.0 (or) 212.216.22.67 | 255.0.0.0
Or does it make a difference? And if not, then what else would be allowing the IP Address to keep on coming in?
That depends on what you want to block.
212.216.22.67 | 255.255.255.255 would block just 212.216.22.67. 212.216.22.67 | 255.255.255.0 would block 212.216.22.0 through 212.216.22.255. 212.216.22.67 | 255.255.0.0 would block 212.216.0.0 through 212.216.255.255. 212.216.22.67 | 255.0.0.0 would block 212.0.0.0 through 212.255.255.255.
There are other combinations, as well. The CIDR lookup tool at http://www.DNSstuff.com will let you enter a CIDR range (which is more common) and show you the netmask. For example, if you enter "212.216.22.67/24", it will show that the netmask should be 255.255.255.0.
