Wildcard mask - Wikipedia
Understanding subnet mask, a fundamental component of IP In the example presented just above, the subnet mask is the same but it can be expressed using three different notations: binary, decimal, CIDR. For the sake of the IP subnetting, it’s fundamental remembering that a decimal value of 255 corresponds to a ‘1111 1111′ so eight bits all set to one. ip - Setting subnet mask to 255.255.255.255 - Network Yes, there's a problem. Your default gateway needs to be in the same subnet as your device. By setting the subnet mask to 255.255.255.255, you've told the computer that nothing else is in its subnet. A more appropriate way to do things would be to set your device IP to 10.0.0.2, your gateway to 10.0.0.1, and your subnet mask to 255.255.255.252. IP Subnet Calculator In IPv6, the network prefix performs a similar function as the subnet mask in IPv4, with the prefix length representing the number of bits in the address. Prior to the introduction of CIDR, IPv4 network prefixes could be directly obtained from the IP address based on the class (A, B, or C, which vary based on the range of IP addresses they
